Here’s a simple explanation of Graham’s Law of Diffusion:
- Definition: Graham’s Law says that lighter gas molecules diffuse faster than heavier ones.
- Key idea: The rate of diffusion of a gas is inversely proportional to the square root of its molar mass.
- In simple terms: If a gas is lighter, it spreads out faster; if it’s heavier, it spreads slower.
Example: Hydrogen gas (H₂) diffuses faster than oxygen gas (O₂) because hydrogen is lighter.
