At Cathode: 2H2O xrightarrow2e- H2 + 2OH- At anode: 2Cl- xrightarrow2e- Cl2 + 2e- (W/E) = (It/96500) 0.1 × 2 = (3 × t(sec)/96500) t = 6433 sec t = 107.2 min ∼ 110 min.

Q. 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

55 minutes

110 minutes

220 minutes

330 minutes

At Cathode:
$2 H_{2} O 2 e^{-} H_{2} + 2 O H^{-}$
At anode:
$2 C l^{-} 2 e^{-} C l_{2} + 2 e^{-}$
$\frac{W}{E} = \frac{I t}{96500}$
$0.1 \times 2 = \frac{3 \times t ( sec )}{96500}$
$t = 6433 sec$
$t = 107.2 min$
$\sim 110 min$ .
