Q. For obtaining chlorine by electrolysis a current of 100 kW and 125 V is used. (Electro chemical equivalent of chlorine is $0.367\ \times {kgC}^{- 1}$). The amount of chlorine obtained in one minute will be

A) 1.7616 g
B) 17.616 g
C) 0.17161 g
D) 1.7616 kg
Explanation

(b) The amount of chlorine
$m = zlt = z\left( \frac{P}{V} \right)\ t\ \ \ \ \ \ \ \ \ \ \ \ \ \lbrack\because P = VI\rbrack$
$\ \ \ \ \ = 0.367 \times 10^{- 6} \times \left( \frac{100 \times 1000}{125} \right) \times 60$
$\ \ \ \ = 0.017616\ kg = 17.616\ g$
