Rate-determining step

Postby Reva Kakaria 1J » Mon Mar 11, 2019 12:14 pm

Given the elementary steps of a reaction mechanism, how are you supposed to figure out which one is the rate-determining/slow step? What kind of information would have to be given to be able to know?

The rate from the rate-determining step must match the overall rate of the reaction. If the coefficients of the rate-determining step are not in line with the powers of the overall rate law for the reaction, then it's not the rate-determining/slow step.
