Consider the reaction: 2NO+2H2N2+2H2O The experimentally derived rate equation is written as follows: r=k[NO]2[H2] A chemist proposes the reaction mechanism below for the reaction: Step 1:2NO+H2N2O+H2O (slow) Step 2: N2O+H2N2+H2O (fast) a) Is this mechanism reasonable? Refer to each of the 3 rules we learned for proposing mechanisms. (3 marks) b) What is the reaction intermediate for this reaction? (1 mark)
