POGIL materials are also available for other STEM disciplines including biology and anatomy and physiology, materials engineering, computer science, and mathematics Information about The POGIL Project, a not-for-profit 501(c)(3) organization, and its activities (including additional materials, workshops, and other professional development opportunities) can be found at http://www.pogil.org New for this edition This 7th edition of Chemistry: A Guided Inquiry is the result of the most substantial changes that we have made to these activities since they were first published over twenty years ago Over the past several years, substantial gains have been made by a variety of colleagues in The POGIL Project – and others – in understanding how to create activities that produce the most learning and the greatest gains in the development of key learning skills such as teamwork, critical thinking, and problem solving We have tried to incorporate as much of these new insights into the structure and organization of these materials as we can Below we list some of the major changes and highlights for this new edition: • Several activities have been restructured to better incorporate a learning cycle structure of exploration, concept invention, and application • Many of the activities now begin with a “Warm-Up” section that students may complete before coming to class In many cases, the activity has been reorganized so that much of the text is now in this “Warm-Up” section, enabling students to read some introductory material before coming to class and reserving more class time for working on the activities with their teammates Instructors may choose to use the “Warm-Up” sections in this way, or they may choose to have the students complete the “Warm-Up” sections as part of the team work during class time • The amount of text has been reduced and restructured to make it easier for students to read and process • Student responses to Critical Thinking Questions are more frequently organized into tables to facilitate analysis and interpretation • The content dealing with electronegativity, partial charge, and dipole moments has been reorganized to reduce repetition and get to the concept of electronegativity sooner The concept of Average Valence Electron Energy is still introduced (in ChemActivity 19) but its relationship to electronegativity is then established directly • Based on research on how students respond to the wording of prompts in these types of activities, we have included more prompts that directly require the students to explain their reasoning and/or analysis We have also included more explicit prompts for students to engage as a team in addressing the questions that are posed Acknowledgments This book is the result of innumerable interactions that we have had with a large number of stimulating and thoughtful people • We greatly appreciate the support and encouragement of the many members of The POGIL Project and the Middle Atlantic Discovery Chemistry Project, who have provided us with an opportunity to discuss our ideas with interested, stimulating, and dedicated colleagues Over the past several years, our colleagues in The POGIL Project have helped us learn a great deal about how to construct more effective and impactful activities; much of what we have learned from them is reflected in the substantially revised activities in this edition • Thanks to the numerous colleagues who used our previous editions in their classrooms Many provided us with insightful comments and suggestions for which we are grateful We are particularly indebted to Professor Gail Webster, Guilford College, who provided us with feedback on every activity in this edition Her thoughtful insights and suggestions had a significant impact on the final product • Many thanks to Jim Spencer, Professor Emeritus, Franklin & Marshall College, for his helpful and insightful discussions, comments, and corrections • A great debt of thanks is due our students in General Chemistry at Franklin & Marshall College over the past two decades Their enthusiasm for this approach, patience with our errors, and helpful and insightful comments have inspired us to continue to develop as instructors, and have helped us to improve these materials immeasurably In particular, RSM thanks the students in his CHM 111 class at Franklin & Marshall College who used the penultimate draft of this book during the fall, 2016 semester Their thoughtful comments and keen eye for typographic errors helped improve this edition and their patience and good humor was greatly appreciated • Thanks to the National Science Foundation (Grants DUE-0231120, 0618746, 0618758, and 0618800) for its initial support of The POGIL Project, a not-for-profit organization that fosters the development and dissemination of guided-inquiry materials and encourages faculty to develop and use student-centered approaches in their classrooms • Special thanks to Dan Apple, Pacific Crest Software, for starting us on this previously untraveled path The Pacific Crest Teaching Institute we attended in 1994 provided us with the initial insights and inspiration to convert our classrooms into fully student-centered learning environments vi • RSM would also like to thank Mark McDaniel, Gina Frey, and all of the staff of the Center for Integrative Research on Cognition, Learning, and Education at Washington University in St Louis A more stimulating sabbatical year could not be imagined, and many of the insights gained from that year were invaluable in improving this

ChemActivity 60 Temperature Dependence of Rate Constants (What Role Does Activation Energy Play?) Model: The Arrhenius Equation The rate of a reaction depends on the temperature because the magnitude of the rate constant, k, is typically a function of the temperature In general, the relationship between k and T is found to be Ea ln k = ln A – RT (1) Here, A is the frequency factor, Ea is the activation energy in units of joules per mole, T is the absolute temperature in Kelvin, and R is the gas constant (8.314 J/mol K) Both A and Ea are characteristic of the particular reaction being studied If the rate constant for a given reaction is examined at two temperatures, T1 and T2, and if the observed rate constants at those temperatures are k1 and k2, respectively, then equation can be used to derive the following relationship: ln º k1 Ea ª = R ôT T ằ 1ẳ k2 (2) Critical Thinking Questions According to equation 1, if the temperature increases, does the rate constant increase or decrease? Explain At how many different temperatures must the rate constant be determined in order to evaluate the activation energy for a reaction? A student is studying a reaction in detail and uses experimental data to calculate that at a given temperature, T, k > A for the reaction Explain why it must be that the student has made an error ChemActivity 60 Temperature Dependence of Rate Constants 381 This same student has determined the value of the rate constant, k, for the reaction at a number of different temperatures She decides to use her data to make a plot of ln k vs 1/T in order to obtain important parameters related to this reaction Based on equation 1, what information can she gain from this plot? Explain your reasoning According to equation 1, if the activation energy for some reaction, Q, is greater than the activation energy for a different reaction, W, which has the greater rate constant—reaction Q or reaction W (assuming that the value of A, the frequency factor, is identical in both reactions)? Explain Exercises A chemist's "rule of thumb" is that the rate of a chemical reaction doubles for every 10 °C increase in temperature Use equation to demonstrate this rule of thumb (assume that a typical chemical reaction has an activation energy of 50 J kJ/mol) Recall that R = 8.314 K mol (Hint: a typical chemical reaction occurs at a typical temperature.) A great Martian chemist enunciated the following chemical principle: The rate of a chemical reaction doubles for every °C increase in temperature Assume that the average temperature on Mars is –40 °C, and determine if the Martian chemist was correct or not Indicate whether the following statement is true or false and explain your reasoning In general, the higher the activation energy, the faster a reaction occurs at a given temperature 382 ChemActivity 60 Temperature Dependence of Rate Constants Problems H2(g) + I2(g) HI(g) The rate constant for the above reaction at two temperatures was determined: Temperature (K) 400 500 Rate Constant (M–1 sec–1) 0.0234 0.750 Determine the rate constant at 400 K for the reverse reaction HI(g) H2(g) + I2(g) as precisely as you can, assuming that A = × 105 M–1 s–1 for the reverse reaction Consider a generic reaction: AB (g) + CD (g) AC (g) + BD (g) a) Construct a reaction coordinate diagram for this reaction assuming that it has a large equilibrium constant, but that it reaches equilibrium very slowly Explain your reasoning clearly b) Indicate how the addition of a catalyst would change the reaction coordinate diagram from part a, and describe what effect this would have on the equilibrium constant and the rate at which equilibrium is reached Appendix TABLE A.1 Values of Selected Fundamental Constants Speed of light in a vacuum
