How is `DeltaG` related to e.m.f. of the cell ?

The e.m.f. of a cell is a

How is DeltaG related yo DeltaH and T DeltaS ? What is the meaning of DeltaG =0 ?

The e.m.f. of a cell is always

The e.m.f. of a cell depends on

Assertion : The e.m.f. of the drivercell in the potentiometer experiment should be greater than the e.m.f. of the cell to determined.

For a cell Ag(s)|AgNO_(3)(0.01M)||AgNO_(3)(1.0M)|Ag(s) (i). Calculate the e.m.f. of the cell at 25^(@)C (ii). Write the net cell reaction. (iii). Will the cell generate e.m.f when two concentrations become equal?

How is DeltaG^(@) related to equilibrium constant?

A cell of e.m.f. 4 V and of negligible internal resistance is connected in series with a potentiometer wire of length 400 cm. The e.m.f. of a Leelanche cell is found to be balacned at 150 cm from the positive end of the potentiometer wire. What is the e.m.f. of the Leclanche cell ?
