Writing the rate law implied by a simple mechanism Suppose the formation of dinitrogen pentoxide proceeds by the following mechanism: step elementary reaction - 1 NO2(g) + O2(g) → NO(g) + O2(g) 2 NO3(g) + NO2(g) → N₂O(g) rate constant k₁ 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. Note: your answer should not contain the concentrations of any intermediates. ☐ rate = ☐ 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 = ☐ Х 5 olo 18 Ar
