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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F40daf55f-9b36-4034-9111-c8b1fc526fc5%2F93fb7b40-f993-458b-9163-8c3c1250f27b%2Fvx3tq2a.jpeg&w=3840&q=75)
