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.

    Exemplo Resolvido

    Compare effusion rates of H₂ (2 g/mol) and O₂ (32 g/mol).

    1. Rate₁/Rate₂ = √(M₂/M₁)
    2. Rate₁/Rate₂ = √(32/2)
    3. Rate₁/Rate₂ = √16
    4. Rate₁/Rate₂ = 4.0
    5. H₂ effuses 4 times faster than O₂
