Assertion : A reaction is spontaneous if E_cell = +ve.

Reason : For E_cell = +ve, $∆$G is always -ve.

• 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

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.
