August undefined, 2024

Graham'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.

WebAug 8, 2024 · Graham's law can be understood by comparing two gases ( A and B) at the same temperature, meaning the gases have the same kinetic energy. The kinetic energy of a moving object is given by the equation K E = 1 2 m v 2 where m is mass and v is velocity. Setting the kinetic energies of the two gases equal to one another gives:

WebEffusion is the movement of gas molecules from one container to another through a tiny hole. Rates of effusion can be compared at the same temperature using Graham’s law.
