Catalysts and Rate Laws

APCHEM-KELUM3

Given the reaction $ A + B \rightarrow C + D$ , a catalyst, $X$, is used to increase the overall reaction and an intermediate, $Y$, is formed during the reaction.

Without actual data, which of the following is LEAST likely to be the rate law for the reaction?

A

$\text{Rate} = k[A][B]$

B

$\text{Rate} = k[A][X]$

C

$\text{Rate} = k[A][Y]$

D

$\text{Rate} = k$
