Answer:

15°

Explanation:

At the lowest temperature the gas will have the lowest rate of diffusion because diffusion deals with the motion of particles.

  • Diffusion is the movement of particles from a region of high concentration to that of a lower concentration.
  • According to the kinetic molecular theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules.
  • The higher the temperature faster the molecules diffuse.

The gas with the lowest temperature will be the slowest to diffuse.

Answer:

15º

Explanation:

The rate of diffusion is lower when the temperature is lower. Since 15º is the lowest temperature of the answers, it has the lowest rate of diffusion.
