Electrolysis of aq. Solution of `CH_(3)COOK` is caried out. If 2 amp current is passed for 402 minutes. What volume (at STP) of gases could be produced if current efficiency is `80%` (assume no absorption of gases)

Answer

`00017.92`

Explanation

`2CH_(3)COOK overset("electrolysis")C_(2)H_(6)+2CO_(2)+H_(2)+2KOH+2H_(2)O`
`Q=2xx402xx60`
moles of `e^(-)=0.5` used mole of `e^(-)=(0.5xx80)/100=0.4`
as 2 mole `e^(-)to 4` mole gases
so `0.4` mole `e^(-)to (0.4xx4)/2=0.8` mole gases
`V=0.8xx22.4` Lt. `=17.92` Lt.
