Ammonium chloride when dissolved in water leads to a cooling sensation. The dissolution of ammonium chloride at constant temperature is accompanied by

A

Increase in enthalpy

B

Decrease in enthalpy

C

No change in enthalpy

D

Both (a) or (b)

Text Solution

Verified by Experts

The correct Answer is:
A
Cooling sensation indicates in temperature. Therefore reaction is endothermic. Therefore, `Delta H` is + ve. Therefore Enthalpy increases.
