Reaction Mechanism and Rate Law

CHEM-CITLHX

Consider the following reaction mechanism:

$$ A + B \xrightarrow [ ] {{ k }_{1}} C$$

$$ B + C \xrightarrow [ ] {{ k }_{ 2 }} \text{products}$$

From experiment, ${k}_{2} > {k}_{1}$.

What is the rate law predicted by this mechanism?

A

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

B

$\text{rate} = k{[B]}^{2}$

C

$\text{rate} = k[C][B]$

D

$\text{rate} = k[A]{[B]}^{2}$

E

$\text{rate} = k[A][B][C]$
