How many atoms of Kr (Krypton) are in a balloon that contains 2.00 mol of Kr? (4)

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.

answer carbon and three oxygen atoms;
