Consider the Reaction 2O₃(g) $\to$ 3O₂(g) $\to$ 2O₂
If We Assume the Second Step of the Mechanism

Consider the reaction 2O₃(g) $\to$ 3O₂(g) .The following mechanism is proposed: O₃ O₂ + O
O₃ + O $\to$ 2O₂
If we assume the second step of the mechanism is the rate determining step and the first step is a fast equilibrium step,which of the following rate laws is predicted by this mechanism?

A) rate = k[O₃]
B) rate = k[O₃]²[O₂]
C) rate = k[O₃]²[O₂]^-1
D) rate = k[O₃]²
E) none of these
