A) 0.66 mol
B) 0.33 mol
C) 0.66g
D) 0.33 g
Correct Answer: C
Solution :
Key Idea: We will use Faraday's law to solve the problem \[\frac{w}{E}=\frac{it}{96500}\] Or \[w=\frac{Eit}{96500}\] Given \[E=35.5,\text{ }i=1A,\] \[t=30\text{ }min=3\times 60\text{ }s\] Substituting values \[w=\frac{35.5\times 1\times 30\times 60}{96500}=0.66g\] \[\therefore \]0.66 g of chlorine is liberated.You need to login to perform this action.
