The coefficients in a reaction equation are not necessarily equal to the reaction orders, whereas the coefficients of an elementary step always equal the reaction orders of its rate law. explain. 2. (8 pts) a reaction can be thermodynamically favorable, but kinetically unfavorable. what does that mean? when is a reaction thermodynamically or kinetically favorable or unfavorable? choose a suitable reaction and draw energy diagrams to explain these concepts. (8 pts) for a reaction the following mechanism was proposed: 3. (1) a+b c (fast) (2) c+d e (slow) (3) +b (fast) a. what is the overall equation? b. identify the intermediate(s) and catalyst(s), if any. c. what are the molecularity and the rate law for each step? d. is the mechanism consistent with the actual rate law: rate k[a][b][d]?
