If r₁, r₂ and r₃ represent the most probable speeds of three different gases at the same temperature as shown in figure with molar masses M₁, M₂ and M₃ respectively. The correct order of molar masses of these gases is

Options

  1. AM₁>M₃>M₂
  2. BM₃>M₂>M₁
  3. CM₂>M₁>M₃
  4. DM₂>M₃>M₁

Correct answer

C. M₂>M₁>M₃

Step-by-step solution

In the direction of x -axis r₃ increases and for same temperature most probable speed 1 molar mass (M) Thus, M₂>M₁>M₃ .
