NO is reduced by hydrogen to give N (g) & H2O vapor. One possible mechanism to account for this reaction is:
Step 1: 2NO (g)<---> N2O2 (g)
Step 2: N2O2 (g) + H2 (g) --> N2O (g) + H2O (g)
Step 3: N2O (g) + H2 (g) --> N2 (g) + H2O (g)
Determine the net reaction, the molecularity of each step and assuming step 3 is rate limiting determine the rate law for the mechanism.© BrainMass Inc. brainmass.com March 4, 2021, 6:14 pm ad1c9bdddf
The molecularity is the number of molecules of reactants
For step 1 the molecularity is 2
The answer to the reaction rate is explained succinctly in the solution.
