... sulfate radicals in this initiation step is really fast, such that the rate of radical formation is the same as the rate of chain initiation. As a result, the equation of initiation rate becomes: ... concentration of propagated radicals. Therefore, if the total concentration of the radicals is assumed to be in a steady state, the initiation rate of propagation for radi...
