Question

Which of the following correctly applies to a reaction mechanism?1. The elementary steps must sum to the overall reaction.2. The rate-determining step limits the overall rate of the reaction.3. Intermediates are shown in both elementary steps and the overall reaction.4. The rate law for the reaction can be predicted by the mechanism.A and B onlyA, B, and C onlyA, B, and D onlyA, B, C, and D

Answer 1

Answer:

A, B and D

Explanation:

The rate determining step decides the overall rate of reaction and the species involved in the rate determining step determine the overall order of reaction. All the elementary steps in the mechanism sum up to give the overall reaction equation. However, transient intermediates only appear in elementary reaction equations and not the overall reaction equation.

Answer 2

Answer:

A and B only
