Answer 1-3. Will give thumbs up

1. For the reaction A2+B22AB,Ea(fwd)=125kJ/mol and Ea(rev)=85kJ/mol. Assuming the reaction occurs in one step, (a) draw a reaction energy diagram;(b) calculate Hrxn; and (c) sketch a possible transition state. 2. Explain why the coefficients of an elementary step equal the reaction orders of its rate law but those of an overall reaction do not. 3. Consider the following mechanism: (1) ClO(aq)+H2O(l)HCLO(aq)+OH(aq) [fast] (2) I(aq)+HClO(aq)HIO(aq)+Claq(aq) [slow] (3) OH(aq)+HIOOq)H2O(I)+IO(aq) [fast] (a) What is the overall equation? (b) Identify the intermediate(s), if any (c) What is the molecularity and the rate law for each step? (d) Is the mechanism consistent with the actual rate law: rate =k[ClO][I]
