The number of correct statements from the following is..............

The number of correct statements from the following is...........
A. Ecell{E}_{cell} is an intensive parameter
B. A negative Eo{E}^{o} means that the redox couple is a stronger reducing agent than the H+/H2{H}^{+} / {H}_{2} couple.
C. The amount of electricity required for oxidation or reduction depends on the stoichiometry of the electrode reaction.
D. 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.

Correct answer

4

Step-by-step 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.

ΔG=−nFEcell\Delta G = - {nFE}_{cell}

The ∆G∆ G in the above equation is an extensive property, Ecell{E}_{cell} is an intensive property. A negative Eo{E}^{o}means that the redox couple is a stronger reducing agent than the H+/H2{H}^{+} / {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.
