MP Board Class 12 Chemistry — Faraday's first law of elect

Q: Faraday's first law of electrolysis states that the mass of a substance deposited at an electrode is proportional to:

The correct option is Quantity of electricity passed. Faraday's first law states that $m = Z \times I \times t$, where $m$ is the mass deposited, $Z$ is the electrochemical equivalent, $I$ is current, and $t$ is time. Thus, mass is directly proportional to the total charge ($Q = I \times t$) passed through the electrolyte.
