Question

How does rate of diffusion change with 1. density of liquid and 2. Temperature? Give examples

Answer 1

Answer:

Temperature and the rate of diffusion have a directly proportional relationship with one another. The rate of diffusion increases as the temperature increases. At higher temperatures, particles move faster because more energy is available to diffuse them.

Since volumes of different gases contain the same number of particles (see Avogadro's Hypothesis), the number of moles per liter at a given T and P is constant. Therefore, the density of a gas is directly proportional to its molar mass (MM). Graham's Law of Diffusion::The rate at which gases diffuse is inversely proportional to the square root of their densities.
