Oxidation of succinate ion produces ethylene and carbon dioxide gases. On passing 0.2 Faraday electricity through an aqueous solution of potassium succinate, what is the total volume of gases (at both cathode and anode) at STP (1 atm and 273 K)?
  1. 8.96 L
  2. 4.48 L
  3. 6.72 L
  4. 2.24 L

Solution



Ethene, CO2, H2 are gases.

So total moles of gas =1+2+1=4

By 2 Farady=4 mole of gas produced

So, by 0.2 Farady =0.4 mole gas produced

ν=nRTP=0.4×0.0821×2731=8.96 L
