Graham's Law of Effusion/Diffusion (r1/r2 = sqrt(M2/M1))
jee-mainjee-advancedneet-ug
r1/r2 = sqrt(M2/M1)
What each symbol means
| Symbol | What it stands for |
|---|---|
| M_i | Molar mass (consistent units, ratio only) |
| r_i | Rate of effusion/diffusion |
When to use this
Same T,P; ideal gas; comparable experimental setup.
