Chlorine, Cl2\text{Cl}_2Cl2, reacts with nitrogen dioxide, NO2\text{NO}_2NO2, to form nitryl chloride, NO2Cl\text{NO}_2\text{Cl}NO2Cl, as shown reactively below:
Cl2+2NO2→2NO2Cl \text{Cl}_2 + 2\text{NO}_2 \rightarrow 2\text{NO}_2\text{Cl} Cl2+2NO2→2NO2ClThe mechanism for this reaction involves two steps. Step 1 is the 'slow' step and Step 2 is the 'fast' step.
The equation for Step 2 is shown below:
Cl+NO2→NO2Cl \text{Cl} + \text{NO}_2 \rightarrow \text{NO}_2\text{Cl} Cl+NO2→NO2ClSuggest the equation for Step 1 and the rate equation for this overall reaction.
