Suppose the reduction of nitric oxide proceeds by the following mechanism: step elementary reaction rate constant 1 H,(9) + 2NO(9) → N,0(9) + H,O(g) 2 H2(9) + N,O(9) → N,(9) + H,O(9) Suppose also k,«k,. That is, the first step is much slower than the second. Write the balanced chemical equation for the overall chemical reaction: 2H, (g) + 2NO(g) → N, (g) + 2H,0(g) Write the experimentally- observable rate law for the overall chemical reaction. rate = k k, [H,][H, 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 k = = k, the reverse of the two elementary reactions in the mechanism.
