Question
Given the potential energy diagram below for the one-step reaction:

\[ X + Y \rightarrow Z + R \]

The arrow labeled "a" represents the _______.

**Diagram Explanation:**

- **Y-axis (Vertical):** Potential energy
- **X-axis (Horizontal):** Reaction coordinate

The diagram shows:

1. **Reactants (X + Y):** Positioned at the start on the potential energy scale.
2. **Products (Z + R):** Positioned lower than the reactants on the potential energy scale.
3. **Transition state:** The peak of the graph (labeled "b").
4. **Arrows:**
   - **a:** From the potential energy of the reactants to the transition state.
   - **b:** Summarizes the transition state's peak.
   - **c:** From the potential energy of the products to the transition state.
   - **d:** Represents the difference between the energy of reactants and the products.

**Multiple Choice Options:**

- Activation energy for the forward reaction
- Net change in energy for the reaction
- Energy content of the reactants
- Energy content of the transition state
- Activation energy for the reverse reaction

Option marked: Activation energy for the reverse reaction.
