### k in Lavelle's Lecture

During the lecture today, why did k = 2k2K = 2k1k2/k'1? I don't get how he derived this formula.

The rate constant for the overall reaction is a combination of the rate constants for elementary steps. After calculating the overall rate law based on the proposed mechanism, we can compare it to the experimentally-determined rate law to get the overall k in terms of k's for the elementary steps.
