In producing chlorine through electrolysis `100 W` power at `125 V` is being consumed. How much chlorine per min is liberated ? `ECE` of chlorine is `0.367 xx 10^(6) kg//C`

Options

A. `1.76 xx 10^(-3) kg`
B. `9.67 xx 10^(-3) kg`
C. `17.61 xx 10^(-3) kg`
D. `3.67 xx 10^(-3) kg`

Answer

C

Explanation

(c ) Mass of the substance deposited at the cathode
`m = zit = z ((W)/(V)) t`
`= 0367 xx 10^(-6) xx (100 xx 10^(3))/(125) xx 60 = 17.6 xx 10^(-3) kg`
