APCHEM-FX8G1Q

For the following mechanisms, which of the following is the correct rate law?

$$NO + NO \longrightarrow N_2O_2 \text{ (slow)}$$

$$N_2O_2+ O_2 \longrightarrow 2NO_2 \text{ (fast)}$$

A

$\text{rate} = k[NO]^2[O_2]$

B

$\text{rate} = k[N_2O_2][O_2]$

C

$\text{rate} = k[N_2O_2]$

D

$\text{rate} = k[NO]^2$
