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

Options

A. 330 minutes
B. 55 minutes
C. 110 minutes
D. 220 minutes

Answer

C

Explanation

At cathode: `2H_(2)O overset(2e^(-))toH_(2)+2OH^(-)`
At anode: `2Cl^(-)to overset(2e^(-))toCl_(2)+2e^(-)`
`(w)/(E)=(It)/(96500)`
`0.1xx2=(3xxt(sec))/(96500)`
t=6433 sec
t=107.2 min=110min
