![**Reaction Profile Explanation**
The reaction profile (not to scale) for the reaction:
\[ \text{C}_2\text{H}_5\text{OH} + \text{Br}^- \rightarrow \text{C}_2\text{H}_5\text{Br} + \text{OH}^- \]
is depicted in the diagram.
**Diagram Analysis:**
- **Y-Axis**: Energy (E) in kJ
- **X-Axis**: Reaction Coordinate
- The diagram shows a peak in energy at 161 kJ, representing the activation energy (Ea) for the reaction.
- The difference in energy between the reactants (\[\text{C}_2\text{H}_5\text{OH} + \text{Br}^-\]) and the products (\[\text{C}_2\text{H}_5\text{Br} + \text{OH}^-\]) is 71 kJ.
**Questions and Choices**
Which of the following are true? Choose all that apply.
- [ ] \(\Delta E\) is negative.
- [ ] The value of \(E_a\) in the presence of a catalyst would be lower than 161 kJ.
- [x] The value of delta \(E\) in the presence of a catalyst would be smaller than 71.0 kJ.
- [ ] The energy of the products is higher than the energy of the reactants.
- [ ] The reaction is endothermic.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fe19fa2ed-8566-4b3b-96d0-3591866fab62%2Fd9a7d96c-5da2-416a-b90d-690cc0787c12%2Ftev7a4j_processed.png&w=3840&q=75)
