WebJul 29, 2024 · Answer: According to Graham’s Law, the square root of a gas’s molar mass has an inverse relationship with the rate of diffusion or effusion of that gas. The equation for this law is shown below. r is inverse proportional to square root of M. In these equations, M = molar mass and r = rate of diffusion or effusion.
