JEE Advanced Model Paper 13 with solutions for online practice

Paragraph for Question Nos. 37 to 38

The standard cell potential (E°cell) of a reaction is related as ΔG° = nFE°cell , where - ΔG° equals maximum electrical work.
n = number of moles of electrons exchanged as per the balanced chemicalequation.
ΔG°r = ΔH°r - TΔS°r ..... (1)
and also

δ(ΔG°r)

δT

= -ΔS°r ..... (2)
