Chromatograph a mixture of three compounds: naphthalene, toluic acid and fluorenol, through an alumina column eluted with a solvent system based on hexanes which becomes more polar with the addition of more and more dicholomethane over tme. a. True
b. False

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.
