How long will it take to produce $5.4 \mathrm{~g}$ of $\mathrm{Ag}$ from molten $\mathrm{AgCl}$ by passing $5 \mathrm{amp}$ current? (Molar mass Ag $=108 \mathrm{~g} \mathrm{~mol}^{-1}$ ) 965
  1. 1930 second
  2. 965 second
  3. 193 second
  4. 9650 second

Solution

$\mathrm{W}=\frac{\mathrm{E}}{\mathrm{F}} \mathrm{It}$ $\begin{aligned} & 5.4=\frac{108}{96500} \times 5 \times t \\ & t=965 \mathrm{sec}\end{aligned}$
