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

Options

A. 8.96 L
B. 4.48 L
C. 6.72 L
D. 2.24 L

Answer

A

Explanation

Total equivalent of
`C_(2)H_(4)+CO_(2)+H_(2)=0.2+0.2+0.2=0.6`
Total moles of gases = `(0.2)/2+(0.2)/1+(0.2)/2=0.4`
`V=(nRT)/P=(0.4xx0.0821xx273)/1=8.96L`.
