Problem

The oxidation of nitrogen dioxide by chlorine gas proceeds by the following mechanism. Step 1 (slow): NO2_2 + Cl2_2 → NO2_2Cl + Cl Step 2 (fast): NO2_2 + Cl → NO2_2Cl What rate law for the overall reaction is predicted by this mechanism? (a) k[NO2][Cl]k[\text{NO}_2][\text{Cl}] (b) k[Cl2]k[\text{Cl}_2] (c) k[NO2][Cl2]k[\text{NO}_2][\text{Cl}_2] (d) k[NO2]2[Cl2]k[\text{NO}_2]^2[\text{Cl}_2]
