Rate Law

Postby PranavKetharam » Sun Mar 17, 2024 3:47 pm

When determining the rate law for the slowest step, is it appropriate to include the intermediate or are we expected to derive the intermediate using the previous step?

you typically do not include intermediates in the rate law expression. Instead, you focus on the reactants and/or any catalysts involved in that particular step

Intermediates and catalysts cancel out when you are combining the equations to get the overall rate. This means they are not included in the final equation or the final rate.

When writing the rate law for the slowest step, it is not appropriate to include the intermediates and instead base the rate law on the reactants. The intermediates are not included in the rate law for the overall reaction since they aren't present in the overall reaction equation, therefore we shouldn't include them at all.

When determining the rate law for the slowest (rate-determining) step in a reaction mechanism, it is generally not appropriate to include intermediates in the rate law expression. Instead, the rate law should be written solely in terms of the reactants and products involved in the rate-determining step.
