CHEMISTRY CALCULATORS
Graham’s Law Calculator
Effortlessly calculate gas diffusion rates using Graham’s law for chemistry enthusiasts.
What is the Graham’s Law Calculator & How does it work?
Graham’s Law of Diffusion describes the rate at which gases diffuse through a medium. According to this law, the rate of diffusion is inversely proportional to the square root of the molar mass of the gas.This means that lighter gases diffuse faster than heavier ones. The law is particularly useful in understanding the behavior of gases in various chemical reactions and processes.
frac{r_1}{r_2} = sqrt{frac{M_2}{M_1}}
r = diffusion rate, M = molar mass

Frequently Asked Questions
What is Graham's Law of Diffusion?
Graham's Law states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
How do I use this calculator for gases with known molar masses?
Input the molar masses of the two gases you want to compare, and the calculator will show you their relative diffusion rates.
Why is Graham's Law important in chemistry?
It helps predict how quickly gases will mix or react based on their molecular weights, which is crucial in many chemical processes.
Can this calculator be used for liquids as well?
No, Graham's Law specifically applies to gases. For liquids, different principles and laws are used.
What does the diffusion rate ratio tell me?
The ratio tells you how much faster one gas diffuses compared to another based on their molar masses.
Are there any limitations to Graham's Law?
Yes, it assumes ideal gases and doesn't account for temperature or pressure variations, which can affect real-world diffusion rates.
How does temperature affect gas diffusion according to Graham's Law?
While not directly addressed by the law itself, higher temperatures generally increase the kinetic energy of gas molecules, leading to faster diffusion rates.
