Assignment:
For the reaction: 2H2(g)+2NO(g)--> N2(g)+2H2O(g)
The observed rate expression is: rate=k[NO]^2[H2]
Which of the following mechanisms is/are consistent with the overall reaction and the rate expression?
a. Single step 2H2 + 2NO --> N2 + 2H2O
b. Step 1 H2 + NO --> H2O + N (slow)
Step 2 N + NO --> N2 + O
Step 3 O + H2 --> H2O
c. Step 1 H2 + 2NO --> N2O + H2O (slow)
Step 2 H2 + N2O --> N2 + H2O
d. Step 1,2 NO (equilibrium arrows)N2O2
Step 2 N2O2 + H2 --> N2O + H2O (slow)
Step 3 N2O + H2 --> N2 + H2O
e. more than one of these mechanism (a-d) is consistent
