The ratio of average speed of a gas molecule to the root mean square speed at a particular temperature is

Options

  1. A2 : 1.08
  2. B1.08 : 1
  3. C1 : 1.08
  4. D1.08 : 2

Correct answer

C. 1 : 1.08

Step-by-step solution

v_ avg = 8RT M , v_ rms = 3RT M v_ avg v_ rms = 8RT/ M 3RT/M = 8 3 = 8 3 3.14159 0.849 1 1.085 v_ avg : v_ rms = 1 : 1.08
