Vedclass · Answer

(A) According to Faraday's $1^{st}$ law of electrolysis,the mass of substance deposited or liberated $(w)$ is given by $w = ZIt$,where $Z$ is the electrochemical equivalent,$I$ is the current,and $t$ is the time. Since $Z = \frac{E}{F}$ (where $E$ is the chemical equivalent and $F$ is Faraday's constant),the equation becomes $w = \frac{EIt}{F}$. Thus,the amount of ion discharged is directly proportional to the current $(I)$,time $(t)$,and chemical equivalent $(E)$. It is inversely proportional to resistance $(R)$ because $I = \frac{V}{R}$,meaning $w \propto \frac{1}{R}$.

The amount of ion discharged during electrolysis is not directly proportional to
