The number of correct statements from the following is : \(A.\) \(E _{\text {cell }}\) is an intensive parameter. \(B.\) A negative \(E^{\Theta}\) means that the redox couple is a stronger reducing agent than the \(H ^{+} / H _2\) 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.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
