MCQ
For a spontaneous process:
- Aenthalpy change of the system must be negative
- Bentropy change of the system must be positive
- Centropy change of the surrounding must be positive
- Dentropy change of the system plus surrounding must be positive
✓
Answer
- entropy change of the system plus surrounding must be positive
Explanation:
For a spontaneous process the randomness of the molecules in the system increases so the entropy change of the system and surroundings must be positive.
