The reaction 2 NO(g) + H2(g) --> N2O(g)
+ H2O(g) proceeds through the following
mechanism:
2 NO(g) --> N2O2(g)
N2O2(g) + H2(g) -->
H2O(g) + N2(g)
(b) What would the rate law be if the first step of this mechanism
were rate-determining?
Rate = k [NO] [H2]Rate = k [NO]2 [H2]
Rate = k [NO] [H2]2Rate = k [NO]1/2 [H2]
Rate = k [NO] [H2]1/2
Rate = k [NO]2
Rate = k [NO]2 [H2]1/2
Rate = k [NO]

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?
