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. 330min
B. 55 min
C. 110 min
D. 220 min

Answer

C

Explanation

At cathode : `2H_(2)O(l) overset(2e^(-))rarr H_(2)(g) + 2OH^(-) (aq)`
At anode: `2Cl^(-)(aq) overset(2e^(-))rarr Cl_(2)(g)+ 2e^(-)`
`(w)/(E)= (l t)/(96500)`
`0.1xx 2= (3 xx t("sec"))/(96500)`
t= 6433 sec `rArr` t= 107.2 min `~=` 110 min
