A 0.200M KOH solutions is electrolysed for 1.5 h using a current of 8.00 A. How many moles `O_2` were produced at the anode?

A

`0.48`

B

0.224

C

`0.112`

D

`2.24 xx 10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
C
96500 coloumbs `to (1)/(4)` moles of `O_2`
`(8 xx 1.5 xx 60 xx 60) to n , n = (8 xx 1.5 xx 60 xx 60)/(96500) xx (1)/(4) = 0.112L`
