Boron shows anomalous behaviour in its groups because of its small size and non-availability of $d$-orbitals.
It resembles silicon and shows a diagonal relationship with it.

$Cu^+ + e^-\to Cu$, $E^o = X_2$
Calculate $E^o$ for $Cu^{+2} + e^-\to Cu^+$

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