Free effusion rate calculator using Graham's Law. Compare gas effusion rates instantly with molar mass and temperature inputs. Perfect for students and scientists.
Rate₁/Rate₂ = √(M₂/M₁) × √(T₁/T₂)
Graham's Law of Effusion states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass. When comparing two gases at the same temperature, the lighter gas will effuse faster than the heavier gas.
The formula also accounts for temperature differences between the gases. Higher temperature increases the average kinetic energy of gas molecules, resulting in faster effusion rates.
