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 )?

Options

  1. A8 . 96   L
  2. B4 . 48   L
  3. C6 . 72   L
  4. D2 . 24   L

Correct answer

A. 8 . 96   L

Step-by-step solution

Ethene, CO 2 ,   H 2 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 = n R T P = 0.4 × 0.0821 × 273 1 = 8.96   L
