- Graham's Law
To discuss this law, please consider samples of two different gases at the same Kelvin temperature. Since temperature is proportional to the kinetic energy of the gas molecules, the kinetic energy (KE) of the two gas samples is also the same. In equation form, we can write this:
Graham's law of effusion indicates that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
Graham's Law of Effusion Examples and Problems only. Return to KMT & Gas Laws Menu. Ten Examples. Example #1: 8.278 x 10¯ 4 mol of an unidentified gaseous substance effuses through a tiny hole in 86.9 s Under identical conditions, 1.740 x 10¯ 4 mol of argon gas takes 81.3 s to effuse.

Do the following problems, showing your work and including all proper units. 1. If neon gas travels at 400 m/s at a given temperature, calculate the velocity of butane, C
1) The rates of effusion of two gases are inversely proportional to the square roots of their molar masses. Here is a statement of Graham's law: rate 12 x MM 1 = rate 22 x MM 2. 2) Solve for the unknown: rate 2 = (rate 12 x MM 1) / MM 2. rate 2 = (1 2 x 46.005) / 64.063. rate 2 = 0.85.
