Correct Answer: Option D
Explanation:
The correct answer is D: endothermic.
Here's why:
The reaction is given with a positive enthalpy change (\(\Delta H = +46.0\) kJ), which indicates that the reaction absorbs heat from the surroundings. A reaction that absorbs heat is called endothermic.
- Endothermic reactions require energy to proceed, and this energy is absorbed from the surroundings, resulting in a positive \(\Delta H\).
- If the reaction had released heat, it would be exothermic, with a negative \(\Delta H\).
Since \(\Delta H\) is positive (46.0 kJ), this means the reaction is endothermic, so option D is correct.
