did you find the answer?

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

"the periodic table is arranged in order of atomic number."
