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

Reason : For Ecell = +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


A.

If both assertion and reason are true and reason is the correct explanation of assertion

For a redox reaction to be spontaneous, the EMF of the cell must be positive.

As, -G = nFEcell

Therefore, for Ecell = +ve, G is always negative.
