14. The reaction 2 H2(g) + 2 NO(g) ® N2(g) + 2 H2O(g) is proposed to have the alternate mechanism: 2 NO(g) ® N2O2(g) FAST N2O2(g) + H2(g) ® N2O(g) + H2O(g) SLOW N2O(g) + H2(g) ® N2(g) + H2O(g) FAST If the rate law is found to be Rate = k[H2][NO]2, could this support the proposed mechanism? Does the rate law indicate that the reaction is termolecular?
