108 g of silver (molar mass 108 g mol–1)...

108 g of silver (molar mass 108 g mol–1) is deposited at cathode from solution by a certain quantity of electricity. The volume (in L) of oxygen gas produced at 273 K and 1 bar pressure from water by the same quantity of electricity is ______.

Text Solution

Verified by Experts

`Ag^(+)+e^(-)Ag downarrow`
If charge deposite 1 mole Ag I.e 108 gm Ag
`implies` Quantity of electricity required =1F
`H_2O+to1/2+2H^(+)2e^(-)`
Here 2 Charge `to1/2 " mole" O_2`
So, If charge `to 1/4 "mole" O_2`
`V_(O_2)=(n_(_O_2)RT)/(P)=(1/4xx0.08314xx273)/1=5.674`litre
