WebSep 10, 2024 · Equation of Graham’s law. Consider two different gases with Molecular masses M 1 and M 2. The rate of their relative diffusion is given by: R 1 ∝ 1/M 1. R 2 ∝ … WebOne application of Graham’s law is the formula obtained for two gases correlating their molar masses and effusion rates: This allows for determining the molar mass of …
WebGraham's law of diffusion (also known as Graham's law of effusion) states that the rate of effusion a gas is inversely proportional to the square root of its molar mass. Often, it is … WebGraham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: =, where: Rate 1 is the rate of effusion for the first gas.
