During the electrolysis of molten sodium chloride, the time required to produce 0.10 mol of chlorine gas using a current of 3 amperes is
A
220 minutes
B
330 minutes
C
55 minutes
D
110 minutes
Explanation
0.1 mol Cl₂ needs 0.2 F of charge.
Detailed Solution
$2Cl^- \rightarrow Cl_2(g) + 2e^-$
$W = \frac{E}{96500}\times it$
$0.1\times71 = \frac{35.5}{96500}\times3\times t(sec)$
t = 6433.33 s = 107.22 min ≈ 110 min
