At a low temperature T0, molecules are bound in pairs by intermolecular forces - they form an associate. When heated to a temperature T = 2T0, the associate disintegrates into molecules. The collision cross section for molecules is k = 1.5 times smaller than the collision cross section for associates. Determine how many times the self-diffusion coefficient of molecules at temperature T differs from the self-diffusion coefficient of associates at temperature T0, if the pressures in both cases are the same.
