Interpreting Potential Energy Diagrams Practice
Graph 1
1. What type of reaction (exothermic or endothermic)
does the graph represent?
2. Calculate the following:
i) ∆H = _________
ii) Ea = __________
3. Would you predict this reaction to happen at room
temperature? List 2 reasons for your answer.
4. Calculate the ∆H and Ea for the reverse reaction.

Graph 3
Consider the following reaction:
A
C
i) What does B represent in the reaction?
ii) Is the overall reaction exothermic or endothermic?
iii) On the graph, draw a line to represent the net
enthalpy change (heat of reaction).
iv) What does [X]F represent?
v) Which step would you expect to be the rate-determining step? Why?
