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

Text Solution

Verified by Experts

The correct Answer is:
D
According to Faraday.s first law:
w = z.i.t
`Z = E/96500` (molar mass)
`0.1 xx 71 = (35.5)/96500 xx 3 xx t` as `xx` factor 2
`t = 110` min
