How is Faraday's second law of electrolysis mathematically demonstrated to be a direct corollary of — Electrochemistry Chemistry Question

💡 Solution & Explanation

According to the first law, $W_1 = Z_1 \times Q$ and $W_2 = Z_2 \times Q$. If the cells are in series, the same charge $Q$ passes through both. Dividing the equations gives $W_1/W_2 = Z_1/Z_2$. Since $Z = E/96500$, substituting this gives $W_1/W_2 = E_1/E_2$, which is the precise mathematical definition of Faraday's second law.
