Question
**Reaction: 2 HI → H₂ + I₂**

The following is a reaction coordinate diagram for the decomposition of hydrogen iodide (HI) into hydrogen gas (H₂) and iodine gas (I₂).

**Diagram Explanation:**

- **Y-Axis (E)**: Represents energy in kilojoules (kJ).
- **X-Axis (Reaction Coordinate)**: Represents the progress of the reaction from reactants to products.

**Key Points:**

- The curve starts at the energy level of the reactants (HI + HI).
- It rises to a peak, indicating the energy of the activated complex. The height from the reactants to this peak is 184 kJ.
- The curve then descends to the energy level of the products (H₂ + I₂), which is 13 kJ above the reactants.

**Questions:**

(Select all that apply.)

1. □ If the energy of the activated complex were increased, ΔE would increase.
2. □ ΔE is negative.
3. □ The magnitude of Ea for the reverse reaction is smaller than 184 kJ.
4. □ The energy of the products is higher than the energy of the reactants.

**Answer Options:**

Review the graph and select the statements that accurately describe the changes in energy throughout the reaction process.
