Suppose the formation of nitrogen dioxide proceeds by the following mechanism: elementary reaction rate constant 2 NO(g) N₂O₂(9) k₁ N₂O₂(g) + O₂(9) k₂ Suppose also k₁ «k₂. That is, the first step is much slower than the second. step 1 2 - Write the balanced chemical equation for the overall chemical reaction: Write the experimentally- observable rate law for the overall chemical reaction. 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. 2 NO₂(g) 0 rate = k k = 0
