Consider the following elementary reaction equation.

2 O_{2}(g) + Cl(g) → ClO(g) + O_{3}(g) → *Assume rate-determining step*

Rate Law:

$\overline{){\mathbf{Rate}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{\mathbf{k}}{\mathbf{\left[}{\mathbf{O}}_{\mathbf{2}}\mathbf{\right]}}^{{\mathbf{2}}}\mathbf{\left[}\mathbf{Cl}\mathbf{\right]}}$

*Concentrations are raised to power of each coefficient*

Consider the following elementary reaction equation.

2O_{2}(g) + Cl(g) → ClO(g) + O_{3}(g)

1. What is the order with respect to O_{2}

2. What is the overall order of the reaction

3. Classify the reaction as a unimolecular, bimolecular, or termolecular.
