Gunnar Tyler · Answer 1

The correct answer is entropy change of the surrounding plus the entropy change of the system must be positive.

Explanation:

The term entropy is a state function. Entropy can be defined as the disorder or randomness of the molecules in a system.

A spontaneous reaction is a type of reaction which deals with the release of free energy. The change of free energy in case of spontaneous reaction is always negative.

According to the second law of thermodynamics a spontaneous reaction will occur in a system if the total entropy of both system and surrounding increases during the reaction.
