What is Graham’s Law of diffusion and effusion of gases. Check out a few examples. Learn its formula, along with a few solved problems. What are its applications.
Graham’s law states that the rate of diffusion or effusion of a gas is inversely proportional to the square root of its density or the square root of its molar mass at a given temperature and pressure.
25 cze 2023 · Graham's law of diffusion states that the ratio of the diffusion rate of two gases is the same as the ratio of the square root of the molar mass of the gases.
1) The first thing we need to do is compute the rate of effusion for each gas: unknown gas: 2.278 x 10¯ 4 mol / 95.70 s = 2.380 x 10¯ 6 mol/s argon: 1.738 x 10¯ 4 mol / 81.60 s = 2.123 x 10¯ 6 mol/s. 2) Now, we are ready to use Graham's Law.
The rate of effusion of a gaseous substance is inversely proportional to the square root of its molar mass. This relationship is referred to as Graham’s law, after the Scottish chemist Thomas Graham (1805–1869).
By applying Graham's Law, scientists and engineers can predict and manipulate the diffusion or effusion rates of gases, allowing for better control and optimization of processes involving gas mixtures.
Graham's law states that the rate of diffusion or of effusion of a gas is inversely proportional to the square root of its molecular weight.
