    In producing chlorine through electrolysis 100 W power at 125 V is being consumed. How much chlorine per minute is liberated? ECE of chlorine is \[0.367\times {{10}^{-6}}kg/C\].

    A)  24.3 mg         

    B)  16.6 mg

    C)  17.6 mg       

    D)  21.3 mg

    Correct Answer: C

    Solution :

    \[P=100W\] and  \[~V=125V\] \[P=VI\] \[\Rightarrow \] \[I=\frac{P}{V}=\frac{100}{125}A\] Mass of chlorine liberated = Zit \[=0.367\times {{10}^{-6}}\times \frac{100}{125}\times 60\] \[=0.0176\times {{10}^{-3}}kg\] \[=17.6mg\]
