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:

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

Answer 1

Answer: (D)

110 minutes

$2C{l}^{-}\to C{l}_2+2e^{-}$

$W=\frac{E}{96500}\times t$

$0.1\times 71=\frac{35.5}{96500}\times 3$

= $6433.33sec$

$=107.22min=110min$
Hence, option $D$ is correct.
