From Wikipedia, the free encyclopedia. In chemical kinetics, the overall rate of a reaction is often approximately determined by the slowest step, known as the rate determining step (RDS) or rate-limiting step.
The catalyst does usually appear in the rate equation. For example, if the rate-determining step in the above reaction scheme is the first step. X + C â XC, the catalyzed reaction will be second order with rate equation v = k cat [X][C], which is proportional to the catalyst concentration [C].
