A vessel contains mixture of hydrogen and oxygen gases in the ratio of their masses equal to (1: 5 ). The ratio of mean kinetic energies of the two gasses is

Options

  1. A(1: 1 )
  2. B(1: 16 )
  3. C(16: 5 )
  4. D(5: 16 )

Correct answer

A. (1: 1 )

Step-by-step solution

Given, (M_ H ₂ : M_ O ₂ =1: 5 ) Mean kinetic energy per molecule, ( aligned & E = 3 2 K_B T & E T aligned ) Hence, mean kinetic energy of gases, depends on the temperature only. Since, temperature of both gases is same. Hence, ratio of their mean kinetic energy will be (1: 1 ).
