JEE Main 2023 — Electrochemistry Question with Solution

An intensive property is a bulk property, meaning that it is a physical property of a system that does not depend on the system size or the amount of material in the system.

$\mathrm{\Delta G}=-{\mathrm{nFE}}_{\mathrm{cell}}$

The $∆\mathrm{G}$ in the above equation is an extensive property, ${\mathrm{E}}_{\mathrm{cell}}$ is an intensive property. A negative ${\mathrm{E}}^{\mathrm{o}}$means that the redox couple is a stronger reducing agent than the ${\mathrm{H}}^{+}/{\mathrm{H}}_2$couple. The amount of electricity required for oxidation or reduction depends on the stoichiometry of the electrode reaction. The amount of chemical reaction which occurs at any electrode during electrolysis by a current is proportional to the quantity of electricity passed through the electrolyte.
