Dinitrogen pentoxide (N2O5\text{N}_2\text{O}_5N2O5) can be produced by the gas-phase reaction of nitrogen dioxide (NO2\text{NO}_2NO2) with ozone (O3\text{O}_3O3) according to the following equation:
2NO2+O3→N2O5+O2 2\text{NO}_2 + \text{O}_3 \rightarrow \text{N}_2\text{O}_5 + \text{O}_2 2NO2+O3→N2O5+O2The proposed mechanism for this reaction occurs in two steps, where Step 1 is the slow, rate-determining step and Step 2 is a fast step.
The equation for Step 2 is shown below:
NO3+NO2→N2O5 \text{NO}_3 + \text{NO}_2 \rightarrow \text{N}_2\text{O}_5 NO3+NO2→N2O5Suggest the equation for Step 1 and determine the rate equation for this overall reaction.
