Statement II : Entropy always decreases in an isolated system.

• A. Statement I is True, Statement II is True and statement II is correct explanation of statements I
• B. Statement I is True, Statement II is True and statement II is NOT correct explanation of statements I
• C. Statement I is True, Statement II is False
• D. Statement I is False, Statement II is True
• E. Statement I is False, Statement II is False

Answer 1

The correct option is E Statement I is False, Statement II is False

Statement I: A positive $△G$ tells you that the reaction is non-spontaneous.

At equilibrium, $△G$ is zero.
Statement II: Entropy may or may not decrease in an isolated system.

Entropy may increase in such system.
