ChemistryEasysingle choice

Assertion : A reaction is spontaneous if $E_{cell} = +$ ve. Reason : For $E_{cell} = + ve, Δ G$ is always -ve.

Options:

Answer:

Solution:

For a redox reaction to be spontaneous, the EMF of the cell must be positive. $As, - Δ G = n F E_{cell}$ Therefore, for $E_{cell} = +$ ve, $Δ G$ is always negative.
