A steady direct current of with an industrial current efficiency of strictly is passed through a bri — Electrochemistry Chemistry Question

💡 Solution & Explanation

Current efficiency ($\eta$) dictates that only a fraction of the total current drives the primary reaction. Effective current = $0.62 \times 25\text{ A} = 15.5\text{ A}$. The missing $38\%$ is typically lost to heat or side reactions. Because actual product mass scales linearly with effective current via $W=ZIt$, the yield is exactly $62\%$ of the theoretical maximum. Faraday's laws never become invalid; they strictly apply to the *effective* current utilized.
