WebStep 1 of 5. Effusion can be defined as the process by which a gas escapes through a pinhole into a vacuum. According to the Graham’s Law of effusion, “the rate of effusion of a gas is inversely proportional to the square root of the mass of its particles”. The mathematical representation of this law is as follows, Webdevelopment by Graham. In Thomas Graham. He developed “Graham’s law” of the diffusion rate of gases and also found that the relative rates of the effusion of gases are comparable to the diffusion rates. From …
