Assume that during the electrolysis of `AgNO3`, only `H_(2)O` is electrolyzed and `O_(2)` is formed as
`2H_(2)O rarr 4H^(o+)+O_(2)+4e(-)`
`O_(2)` formed at `NTP` due to passage of 2 amperes of current for 965 second is

Options

A. `0.112 L`
B. `0.224L`
C. `11.2L`
D. `22.4L`

Answer

a

Explanation

`ZIt or El t. [{:(Ew,of ,O_(2),=,(32)/(4)),(n,fact o r,,=,4):}]`
`W_((O_(2)))=(32xx2xx965)/(4xx96500)`
`=0.16g=0.005mol=0.112L at STP`.
