Electrochemistry

The number of correct statements from the following is __________

A. \(\mathrm{E_{\text {cell }}}\) is an intensive parameter

B. A negative \(\mathrm{E}^{\ominus}\) means that the redox couple is a stronger reducing agent than the \(\mathrm{H}^{+} / \mathrm{H}_{2}\) 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.
