Question:
Which of the following reactions are endothermic and spontaneous?
Which of the following reactions are endothermic and spontaneous?
Show Hint
Check both the enthalpy and entropy changes for the spontaneity and nature of the reaction.
Updated On: May 9, 2025
- (ii) only
- (ii), (v) only
- (iii), (v) only
- (iii), (v)
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
An endothermic reaction absorbs heat, while a spontaneous reaction proceeds without the need for external influence. The reactions in (ii) and (v) are both endothermic and spontaneous based on the enthalpy and entropy changes, making them the correct choice.
