Question

During the electrolysis of molten sodium chloride, the time required to produce 0.10 mol of chlorine gas using a current of 3 amperes is approximately:

• A. 220 minutes
• B. 330 minutes
• C. 55 minutes
• D. 110 minutes

Answer 1

The correct option is D 110 minutes

$2C{l}^{-}\to C{l}_2\left(g\right)+2e^{-}W=\frac{E}{96500}\times it0.1\times 71=\frac{35.5}{96500}\times 3\times t\left(sec\right)t\left(s\right)=6433.33sect\left(min\right)=107.22min\approx 110min.$
