What is Graham's Law?
Key concepts of gas effusion:
- Rate proportional to velocity
- Inverse square root relation
- Molecular mass dependence
- Temperature independence

Calculate the ratio of effusion/diffusion rates for two gases.
Find unknown molar mass using known rate ratio and reference mass.
Calculate the ratio of effusion times for two gases.
Key concepts of gas effusion:
Understanding rate ratios:
Measuring effusion:
Graham's Law is used in:
r₁/r₂ = √(M₂/M₁)
Where M is molar mass
t₁/t₂ = √(M₁/M₂)
Inverse of rate ratio
M₂ = M₁(r₁/r₂)²
From known rate ratio
