State
Assuming effusion rate scales directly with molar mass, rather than inversely with its square root, misreads Graham's law and reverses which gas effuses faster.
Show
A student expecting the heavier gas to effuse faster, reasoning it has "more mass to push through," gets the ranking backward.
Watch for
Graham's law's inverse-square-root relationship means the lighter gas always effuses faster, never the heavier one.
