A) 100s
B) 500s
C) 1000s
D) 2000s
Correct Answer: C
Solution :
Key Idea: Use the formula W = Zit where W = mass of element liberated at cathode \[=0.5\,g\] Given, \[W=0.5g\] \[Z=Eq.\text{ }wt/96500=96.5/96500\] \[i=0.5A\] \[t\text{ }=?\] W = Zit Or \[t=\frac{W}{Zi}=\frac{0.5}{\frac{96.5}{96500}\times 0.5}\] \[=\frac{0.5\times 96500}{96.5\times 0.5}\] \[=1000\,s\]You need to login to perform this action.
