![**Question 16 of 20**
**Problem Statement:**
What is ΔH (in kJ/mol) for a reaction where the activation energy is 250 kJ/mol, while the activation energy for the reverse reaction is 110.0 kJ/mol?
**Explanation:**
To find ΔH, use the formula:
\[ \Delta H = \text{Activation Energy (forward)} - \text{Activation Energy (reverse)} \]
Given:
- Activation Energy (forward) = 250 kJ/mol
- Activation Energy (reverse) = 110.0 kJ/mol
**Calculation:**
\[ \Delta H = 250 \, \text{kJ/mol} - 110.0 \, \text{kJ/mol} \]
\[ \Delta H = 140.0 \, \text{kJ/mol} \]
### Interface Description:
- The image shows a calculator interface for inputting the answer in kJ/mol.
- Number pad includes digits 0-9, a decimal (.), a +/- button, a backspace (×) button, a clear (C) button, and a multiplication by 10 (x10^□) function.
**Note:**
