Which of the following statements is true.

AAll spontaneous processes are exothermic.
BAll non spontaneous processes are endothermic
CAll spontaneous processes release free energy.
DEntropy always increase in a spontaneous process.

Verified Answer :

Answer: The correct answer is Option C.

Explanation:

Spontaneous reactions are defined as the reactions in which Gibbs free energy change is always negative and when Gibbs free energy change is positive, the reactions are known as non-spontaneous reactions.

Exothermic reactions are the reaction in which enthalpy change is negative and when the enthalpy change is positive, they are known as endothermic reactions.

Spontaneous reactions can be exothermic as well as endothermic.

It is not always that when entropy increases, reaction will be spontaneous. There are cases when the entropy is getting decreased but the reaction is still spontaneous.

Hence, the correct answer is Option C.

All spontaneous processes releasing free energy is a True statement.

What is a Spontaneous process?

This is the process which occurs without the need to input matter or any external source of energy.

A spontaneous process could either be endothermic or exothermic and the release of free energy commonly occurs which makes option C the most appropriate choice.
