Question

when temperature increases, the random movement of molecules increases which subsequently increases diffusion rate. if you have the same concentration of each of the following substances and they all have the same molecular weight, predict which substance will have the greatest diffusion rate? multiple choice substance #1 in a semisolid at 78°f substance #2 in a liquid at a 32°f substance #5 in a gas at 78°f substance #4 in a gas at 32°f substance #3 in a liquid at 64°f

Explanation:

Diffusion rate is higher in gases compared to liquids and semisolids. Also, higher temperature increases the diffusion rate. Substance #5 is a gas at the highest temperature among the options.

Answer:

substance #5 in a gas at 78°F
