Question

Oxidation of succinate ion produces ethylene and carbon dioxide gases. On passing $0.2$ Faraday electricity through an aqueous solution of potassium succinate, the total volume of gases (at both cathode and anode) at STP ($1$ atm and $273K$) is 5L.

• A. True
• B. False

Answer 1

The correct option is B False

$KCOO-C{H}_2-C{H}_2-COOK+2H_{2}O⟶\underset{anode}{C{H}_2=C{H}_2}+2C{O}_2+H_2+\underset{cathode}{2KOH}$

Total equivalents of $C_2{H}_4+C{O}_2+H_2=0.2+0.2+0.2=0.6$

Total moles of gases $=\frac{0.2}{2}+\frac{0.2}{1}+\frac{0.2}{2}=0.4$

$V=\frac{nRT}{P}=\frac{0.4\times 0.0821\times 273}{1}=8.96L$
