Assertion : Entropy is always constant for a closed system.
Reason : Closed system is always reversible.
If both assertion and reason are true and reason is the correct explanation of assertion
If both assertion and reason are true but reason is not the correct explanation of assertion
If assertion is true but reason is false
If both assertion and reason are false.
The relation between H and E is :
E = H + nRT
H = E - nRT
H = E + nRT
E = H + nRT
