For a rigid diatomic molecule, the universal gas constant R = n C P , where, C P is the molar specific heat at constant pressure and n is a number. Hence, n is equal to

Options

  1. A0 . 2257
  2. B0 . 4
  3. C0 . 2857
  4. D0 . 3557

Correct answer

C. 0 . 2857

Step-by-step solution

For rigid diatomic molecule C P C V = 7 5 ∴ C V = 5 7 C P Also C P - C V = R C P - 5 7 C P = R 2 7 C P = R ∴ n = 2 7 = 0.2857
