When aqueous solution of sodium ethanoate is electrolysed, the volume of gases obtained at cathode at apressure of 1.0 bar and 298 K temperature when 2.0 Faraday of electricity is passed is:

For 2e- or 2F,3 mol of gases 12 mol of CO2, + 1 mol of CH3-CH3 (g)l are produced.At 1.0 bar pressure and 298 K, volume of 1 mol of gas :24.7 litres.∴ Volume of gases at anode = 24.7 x 3 : 74.L litres
