Solution

The correct option is B
Electrical work = Potential difference $\times$ charge flown
= 1V $\times$ 96500 C
= 1.0J/C $\times$ 96500 C ( $∵$ V = J/C)
= 96,500 J

Q. Electrical work done in one second is equal to electrical potential multiplied by total charge passed. If we want to obtain maximum work from a galvanic cell then charge has to be passed reversibly. The reversible work done by a galvanic cell is equal to decrease in its Gibbs energy and therefore, if the emf of the cell is E and nF is the amount of charge passed and

Δ_{r} G

is the Gibbs energy of the reaction, then

Δ_{r} G = {n F E}_{(c e l l)}

It may be remembered that

E_{(c e l l)}

is an intensive parameter but

Δ_{r} G

is an extensive thermodynamic property and the value depends on n. Thus, if we write the reaction.
