Question

The total entropy change for a system & its surroundings is greater than 0 if the process is :

• A. reversible
• B. irreversible
• C. exothermic
• D. endothermic

Answer 1

The correct option is B irreversible

In an irreversible process, the total entropy change of the universe is greater than zero, thus the entropy change of the system and its surroundings will be positive.

Hence, the total entropy change for a system and its surroundings is greater than zero if the process is irreversible.

Therefore, option B is correct.
