5. Assume the following reaction has a one-step mechanism: A+B → C (a) Draw a potential energy diagram for the reaction that correctly incorporates each of the following labels: AH = -50 kJ/mol Ea(fwd) = 300 kJ (2 Marks) Potential energy ,Reaction progress ,Transition state,A + B,C (b) Is the reaction endothermic or exothermic? (1 Mark) (b) Determine Ea(rev) for the reaction. Add this value to your diagram. (Mark) (c) How would your diagram have been different if the reaction had a two-step mechanism? Explain your answer. (1 Mark) (d) A catalyst speeds up the reaction by providing an alternative, two-step mechanism. On your diagram, sketch a curve to represent the effect of the catalyst on the reaction. (1 Mark)
