The reaction: 2NO2Cl(g)→2NO2(g)+Cl2(g)2\text{NO}_2\text{Cl}(\text{g}) \rightarrow 2\text{NO}_2(\text{g}) + \text{Cl}_2(\text{g}) is believed to have the following mechanism. step 1: NO2Cl(g)→NO2(g)+Cl(g)\text{NO}_2\text{Cl}(\text{g}) \rightarrow \text{NO}_2(\text{g}) + \text{Cl}(\text{g}) slow: the rate-determining step step 2: NO2Cl(g)+Cl(g)→NO2(g)+Cl2(g)\text{NO}_2\text{Cl}(\text{g}) + \text{Cl}(\text{g}) \rightarrow \text{NO}_2(\text{g}) + \text{Cl}_2(\text{g}) fast overall: 2NO2Cl(g)→2NO2(g)+Cl2(g)2\text{NO}_2\text{Cl}(\text{g}) \rightarrow 2\text{NO}_2(\text{g}) + \text{Cl}_2(\text{g}) Deduce the rate equation and the overall order of the reaction.
