Grahams Law Of Effusion

Loading image...

The rate of effusion of a gas is inversely proportional to the square root of its molar mass

Real World Example

Imagine you're trying to catch a bus across town, but you have a heavy backpack weighing you down. Just like it's harder for you to move quickly with a heavy bag, a gas with a higher molar mass moves more slowly through a small opening. The connection here is that your speed is limited by the weight you carry, much like how the rate of effusion of a gas is slower when its molar mass is larger, demonstrating the inverse relationship in Graham's law.
