Nitrogen monoxide reacts with H2 according to the following reaction: 2NO(g)+2H2(g)N2(g)+2H2O(g) The following mechanism is proposed: 2NO(g)N2O2(g)N2O2(g)+H2(g)N2O(g)+H2O(g)N2O(g)+H2(g)N2(g)+H2O(g)fastslowfast Use the above information to answer the next two questions. 1. The observed rate law that is consistent with this mechanism would be: A. second order in NO and zeroth order in H2. B. second order in NO and first order in H2. C. first order in NO and second order in H2. D. second order in NO and second order in H2. E. first order in NO and first order in H2. 2. How would the reaction rate change when both [NO] and [H2] are doubled? A. Reaction rate stays the same. B. Reaction rate increases by a factor of 2. C. Reaction rate increases by a factor of 4 . D. Reaction rate increases by a factor of 6 . E. Reaction rate increases by a factor of 8
