(A) $A.$ $E_{cell}$ is an intensive property because it does not depend on the amount of matter present in the system.$B.$ $A$ negative $E^{\Theta}$ value indicates that the species is a better reducing agent than $H_2$ gas.$C.$ According to Faraday's laws,the amount of electricity required is determined by the number of moles of electrons involved in the balanced half-reaction,which is defined by the stoichiometry.$D.$ This is the definition of Faraday's first law of electrolysis,which states that the mass of substance deposited or liberated is directly proportional to the quantity of electricity passed.Therefore,all four statements are correct.

The number of correct statements from the following is :
$A.$ $E_{cell}$ 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.

Plotting $1 / \Lambda_{m}$ against $c \Lambda_{m}$ for aqueous solutions of a monobasic weak acid $(HX)$ resulted in a straight line with $y$-axis intercept of $P$ and slope of $S$. The ratio $P / S$ is
$[\Lambda_{m} =$ molar conductivity
$\Lambda_{m}^{\circ} =$ limiting molar conductivity
$c =$ molar concentration
$K_{a} =$ dissociation constant of $HX$ ]
