According to Faraday's law of electrolysis, what is the relationship between the amount of substance transformed and electric charge?

• A. The two are inversely proportional
• B. The two are unrelated
• C. They are directly proportional
• D. They vary based on temperature

Answer: (C)

The correct relationship according to Faraday's law of electrolysis is that the amount of substance transformed during electrolysis is directly proportional to the electric charge passed through the system. This law states that the mass of an element transformed at an electrode is proportional to the total electric charge that passes through the cell. Specifically, it can be expressed mathematically as: m = (Q * M) / (n * F) where m is the mass of the substance transformed, Q is the electric charge, M is the molar mass of the substance, n is the number of electrons transferred per mole of substance, and F is Faraday’s constant (the charge of one mole of electrons). This direct proportionality highlights how more electric charge will lead to a greater amount of substance transformed, reflecting the fundamental principle of conservation of mass and charge in electrochemical reactions. Therefore, as the charge increases, the corresponding transformation of the substance similarly increases, confirming the direct proportionality highlighted in the correct answer.
