Ellie Mint is trying to determine the reaction mechanism for the following reaction: 2 H2 + 2 NO—>N2 + 2 H2O Ellie Mint has experimentally determined that the rate law for this reaction is: Rate = k[H2][NO]^2 Ellie Mint has proposed the following mechanism for the overall reaction: Step 1: H2 + NO—>H2O + N (slow) Step 2: N + NO —>N2 + O (fast) Step 3: O + H2 —>H2O (fast) A) Do the steps of this mechanism add up to the overall reaction? (show your work) B) What is the rate law based on this reaction mechanism? C) Based on your analysis, is Ellie Mint’s proposed reaction mechanism plausible? Why or why not?
