Vedclass · Answer

(D) Graham's Law of diffusion states that the rate of diffusion $(r)$ of a gas is inversely proportional to the square root of its molar mass $(M)$ or density $(d)$: $r \propto \frac{1}{\sqrt{M}}$.The rate of diffusion $(r)$ can be expressed as:$r = \frac{V}{t}$ (Volume diffused per unit time)$r = \frac{n}{t}$ (Number of moles/molecules diffused per unit time)$r = \frac{m}{t}$ (Mass diffused per unit time)However,the decrease in pressure per unit time is not a standard definition used in the calculation of the rate of diffusion in Graham's Law.

Which of the following is not considered in the calculation of the rate of diffusion according to Graham's Law?
