A flask contains argon and chlorine in the ratio of 2: 1 by mass. The temperature of the mixture is 27^ C . The ratio of average kinetic energies of two gases per molecule is

Options

  1. A1:1
  2. B2:1
  3. C3:1
  4. D6:1

Correct answer

A. 1:1

Step-by-step solution

(a) The average kinetic energy of molecules is given by KE _ av = 3 2 K T . So it depends only on temperature KE ₁: KE ₂=1: 1
