Geo-Scientist Prelims 2021 Chemistry Q58: If ΔG = ΔH – TΔS and Δ G = Δ H + T((δ(Δ G))/(δ T))P then the…

If ΔG = ΔH – TΔS and \(\Delta G = \Delta H + T\left(\frac{\delta(\Delta G)}{\delta T}\right)_P\) then the variation of emf of cell (E°) with temperature T at constant pressure is given by:

1. (a) \(\frac{\Delta H}{nF}\)
2. (b) \(\frac{\Delta G}{nF}\)
3. (c) \(\frac{\Delta S}{nF}\)
4. (d) \(-\frac{\Delta S}{nF}\)
