3 mole of hydrogen is mixed with 1 mole of neon. The molar specific heat at constant pressure is

Options

  1. A9 R 4
  2. B9 R 2
  3. C13 R 4
  4. D13 R 2

Correct answer

C. 13 R 4

Step-by-step solution

For mixture, C_V= n₁ C_ V₁ +n₂ C_ V₂ n₁+n₂ = 3 5 2 R+1 3 2 R 3+1 = 9 R 4 C_P=C_V+R= 9 R 4 +R= 13 R 4
