In the molecule XeF2, how many pairs of electrons surround Xe and what is the molecular geometry?

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.

increased stability in the completion of fluorine's outer shell.

just did the assignment and the answer was #1 +2 n
