Equal masses of methane and ethane have their total translational kinetic energy in the ratio 3 : 1, then their temperatures are in the ratio is

Options

  1. A5: 8
  2. B45: 8
  3. C15: 8
  4. D8: 5

Correct answer

D. 8: 5

Step-by-step solution

E 1 = 3 2 × M 16 R T 1 E 2 = 3 2 × M 30 R T 2 ⇒ E 1 E 2 = 30 16 T 1 T 2 ⇒ 3 1 = 30 16 T 1 T 2 ⇒ T 1 T 2 = 8 5
