Graham-Gesetz-Rechner — Formel
## Graham's Law of Effusion
### Formula
**Rate₁ / Rate₂ = √(M₂ / M₁)**
Where:
- **Rate₁, Rate₂** = effusion rates of gas 1 and gas 2
- **M₁, M₂** = molar masses of gas 1 and gas 2
Lighter gases effuse faster. The rate is inversely proportional to the square root of molar mass.

Lösungsbeispiel
Compare effusion rates of H₂ (2 g/mol) and O₂ (32 g/mol).
- Rate₁/Rate₂ = √(M₂/M₁)
- Rate₁/Rate₂ = √(32/2)
- Rate₁/Rate₂ = √16
- Rate₁/Rate₂ = 4.0
- H₂ effuses 4 times faster than O₂
