Question

reaction profile is for a reaction at 415 K that occurs at constant pressure.

-There are two intermediates formed during the course of this reaction (at regions A and C).

-There is an intermediate formed at region B.

-This reaction takes place in two steps.

-The first step of the reaction is rate limiting.

-There is an activated complex formed at region B.

-The second step of the reaction is rate limiting.

-There is one transition state formed during this reaction (at region B).

-This reaction is endothermic.

-Heating this reaction will cause all of the Ea values to decrease.

B. Given the mechanism listed below: What is the actual rate law for this reaction?

True statements

There is an intermediate formed at region B.

This reaction takes place in two steps.

The second step of the reaction is rate limiting.

B) in slow step, ony one reactant A is involved hence it is first order with respect to A only

Rate = k[A]
