Question
Assertion: Thechemicalreaction,3H2(g)+N2(g) →2NH3 shows decrease in entropy.
Reason: The process passes into equilibrium state when DGT,P becomes zero.
- If both Assertion and Reason are true and the Reason is correct explanation of the Asser- tion.
- If both Assertion and Reason are true but Rea- son is not correct explanation of the Asser- tion.
- If Assertion is true but the Reason is false.
- If Assertion & Reason both are false
The correct answer is: If both Assertion and Reason are true but Rea- son is not correct explanation of the Asser- tion.
