Problem

Consider the following elementary reaction equation.

NO3(g) + CO(g) → NO2(g) + CO2(g)

a. What is the order with respect of NO3?

b. What is the overall order of the reaction?

c. Classify the reaction as unimolecular, bimolecular, or termolecular.

Solution

Recall:
Rate order - relates the rate of a reaction to the concentrations of its reactants. So in determining rate order, we just look at the reactants.
Elementary reaction - occurs in one step. The order of any reactant in an elementary reaction is equal to its stoichiometric coefficient.
Molecularity - is the number of molecules involved in an elementary reaction. An elementary reaction can be uni- (1), bi-(2), or termolecular (3).

For the reaction NO3(g) + CO(g) → NO2(g) + CO2(g)
