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
- A 1930 second
- B 965 second
- C 193 second
- D 9650 second
Answer & Solution
Correct Answer
(B) 965 second
Step-by-step Solution
Detailed explanation
\(\mathrm{W}=\frac{\mathrm{E}}{\mathrm{F}} \mathrm{It}\)
\(\begin{aligned} & 5.4=\frac{108}{96500} \times 5 \times t \\ & t=965 \mathrm{sec}\end{aligned}\)
\(\begin{aligned} & 5.4=\frac{108}{96500} \times 5 \times t \\ & t=965 \mathrm{sec}\end{aligned}\)
