State
Since effusion rate tracks molecular speed and lighter molecules move faster at equal kinetic energy, kinetic-molecular theory derives Graham's inverse-square-root relationship directly.
Show
At identical temperature, kinetic-molecular theory predicts helium's higher root-mean-square speed accounts for exactly the same rate advantage Graham's law describes empirically.
Watch for
This derivation shows Graham's law follows from the same postulates as the other gas laws, not a separate coincidence.
