Question

7) Answer the following questions based on the potential energy diagram shown here: a) Does the graph represent an endothermic or exothermic reaction? Circle one. b) Clearly label in the graph to the right the position of the reactants, products and Energy of activation. c) Determine the heat of reaction, ?H (enthalpy change) for this reaction. I'm looking for an actual number here. d) How much energy is absorbed by the Energy of activation? Again, an actual numerical value. PE (kJ) 100 80 60 40 20 A + B C + D Progress of the reaction E. Briefly explain how the addition of a catalyst will effect this reaction?
