IfDelta G = Delta H - T Delta S and Delta G = Delta H + T [ (d(Delta G))/(dT) ]_P then variation of EMF of cell , with temperature T, is given by

Answer»

`(DELTA S)/(nF)`
`-(Delta S)/(nF)`
`(DELTAH)/(nF)`
`(Delta G)/(nF)`

Solution :On comparison
` Delta S = - [ (d (Delta G) )/(dT)] , Delta S = - (d (-NFE))/(dT) = nF ((dE)/(dT))`
` THEREFORE ((dE)/(dT)) = (Delta S)/(nF)`
