Assertion (A): The dissolution of gases ...

Assertion (A): The dissolution of gases in water is always an endothermic process.
Reason (R ) : The dissolution of gases in water proceed with a negative value of `DeltaS`.

A

If both `(A)` and `(R )` are correct, and `(R )` is the correct explanation of `(A)`.

B

If both `(A)` and `(R )` are correct, but `(R )` is not the correct explanation of `(A)`.

C

If `(A)` is correct, but `(R )` is incorrect.

D

If `(A)` is incorrect, but `(R )` is correct.

Text Solution

Verified by Experts

The correct Answer is:
D
The dissolution of gasses in water requires energy, hence it is endothermic in nature, but during dissolution entropy may increase or decrease.
