... dehydrogenation of ethane over a suitable catalyst (yet to be found). Pure ethane will be fed to a reactor and a mixture of acetylene, hydrogen, and unreacted ethane will be with- drawn. The reactor will ... process involving standard states for both the final and initial conditions of the system. In a similar manner one can determine standard enthalpy (AH 0 ) and stan- dard e...
