Question
### Diagram Description The diagram is a graph illustrating a chemical reaction's progress. The vertical axis is labeled "Energy," while the horizontal axis is labeled "Reaction." The graph features a curve that shows the energy changes during the reaction. Key points on the graph: - Point 1 to 3: The reaction starts at a lower energy level, rising sharply to point 3, indicating the activation energy needed for the reaction to proceed. - Point 3: The peak of the curve is labeled with "b" and represents the transition state of the reaction. - Point 5: After reaching the transition state, the energy decreases to a lower level, indicating the formation of products. Labels on the graph: - "a" marks the energy difference between the reactants and the transition state. - "b" marks the activation energy for the forward reaction. - "c" marks the energy difference between the reactants and products, representing the enthalpy change of the reaction. - "4" signifies the pathway for the reverse reaction. - Arrow "d" shows the effect of adding a catalyst, which would lower the activation energy. ### Questions a. Which number/letter identifies the enthalpy of the reaction? b. Which number/letter identifies the \(E_a\) of the reaction in the reverse direction? c. Which number/letter identifies the transition state? d. Adding a catalyst would affect which number/letter? Write your answers in order.
