A) \[27h\]
B) \[8.3h\]
C) \[11h\]
D) \[16h\]
Correct Answer: D
Solution :
\[W=60g\] \[i=5A\] Equivalent weight of \[Ca=\frac{atomic\,\,weight}{valency}\] \[=\frac{40}{2}=20\] According to first law of Faraday electrolysis: \[W=Zit=\frac{equivalent\,\,weight}{96500}\times i\times t\] \[\therefore \] \[6=\frac{20}{96500}\times 5\times t\] \[t=\frac{96500\times 60}{20\times 5}s\] \[=\frac{96500\times 60}{20\times 5\times 60\times 60}h\]
