For the reaction coordinate diagram at 27C below, estimate the energies to the nearest +/- 5 kJ i) How many elementary steps in the reaction mechanism ? Type numerical value, 0, 1, 2, 3... ii) Which step is rate limiting? Type Oth, 1st, 2nd, 3rd, 100 80 60 40 20 Energy Energy (kJ) M M iii) is the second elementary step exothermic or endothermic ? 0 -20 40 Type exothermic or -60 2 0 2 in 12 14 endothermic 8 Reaction progres iv) What is the energy of the reaction for the second elementary step? AH2 = kJ Type numerical value & round to nearest 5 kJ v) What is the energy of the intermediate? E int = kJ Type numerical value & round to nearest 5 kJ vii) For a pre-exponential factor equal to 3.209e24 s-1, what is the rate constant for this reaction include units. (5 pts) K = Type numerical value & round to two sig figs. units = Type correct units viii What is the overall order for this reaction? Type Oth, 1st, 2nd, 3rd
