(A) At Anode: $^-OOC-CH_2-CH_2-COO^- \rightarrow CH_2=CH_2 + 2CO_2 + 2e^-$. For $2 \ F$ electricity,$3 \ moles$ of gas ($1 \ mole \ C_2H_4$ and $2 \ moles \ CO_2$) are produced.At Cathode: $2H_2O + 2e^- \rightarrow H_2 + 2OH^-$. For $2 \ F$ electricity,$1 \ mole \ H_2$ gas is produced.Total moles of gas for $2 \ F = 3 + 1 = 4 \ moles$.Total moles of gas for $0.2 \ F = (4/2) \times 0.2 = 0.4 \ moles$.Total volume at $STP = 0.4 \times 22.4 = 8.96 \ L$.
