Question

Suppose the formation of nitrogen dioxide proceeds by the following mechanism: step | elementary reaction | rate constant 1 | 2 NO(g) -> N2O2(g) | k1 2 | N2O2(g) + O2(g) -> 2 NO2(g) | k2 Suppose also k1 << k2. That is, the first step is much slower than the second. Write the balanced chemical equation for the overall chemical reaction: Write the experimentally-observable rate law for the overall chemical reaction. rate = k Note: your answer should not contain the concentrations of any intermediates. Express the rate constant k for the overall chemical reaction in terms of k1, k2, and (if necessary) the rate constants k-1 and k-2 for the reverse of the two elementary reactions in the mechanism. k =
