$A.$ $E _{\text {cell }}$ 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.
