Answer:

None of the above statements is True

Explanation:

  • According to Graham's law, the effusion rate and the square root of the molecular mass of a gas are inversely proportional. Therefore, heavy gas particles diffuse slower compared to light particles which effuse at a faster rate.
  • Particles of different masses have varying average speeds at a given temperature. Large molecules effuse at a slower rate compared to smaller molecules.
  • The diffusion rate of a gas increases with an increase in temperature because higher temperature increases the kinetic energy of particles of the gas making them move faster.
