If `Delta G = Delta H - T Delta S and Delta G = Delta H + T [ (d (Delta G ))/(dT)]_(p)` then variation of EMF of a cell, E, with temperature T, is given by,

Options

A. `(Delta H)/(nF)`
B. `(Delta G)/(nF)`
C. `(Delta S)/(nF)`
D. `(Delta S)/(nF)`

Explanation

On comparison `: Delta S =- [ (d (Delta G ))/( dT)] , Delta S =- (d ( n- n FE))/( dT) = nF ((dE)/( dT)) [{:("Here E is the"),("emf of cell"):}]therefore ((dE)/( dT)) = (Delta S)/(nF)`
