WebFormula for Graham’s Law of Diffusion and Effusion. r ∝ 1/ (M)½. where, r = rate of diffusion or effusion. M = molar mass. The Molar Mass tells you the number of grams per mole of a compound. The units for molar mass is grams/mole. It indicates the number of atoms, ions, molecules, or formula units present in a particular chemical. Graham's law of effusion (also called Graham's law of diffusion) was formulated by Scottish physical chemist Thomas Graham in 1848. Graham found experimentally that the rate of effusion of a gas is inversely proportional to the square root of the molar mass of its particles. This formula is stated as: ,

WebGraham’s diffusion law formula is derived from this statement. It can be used to compare the rates of two gases at a constant temperature and pressure. Assume that r1 and r2 are the Effusion rates of two gases, and M1 and M2 are the molar masses. As a result, the formula can be written like this: r1/r2 = √M1/M2 Calculation of the Rate of Diffusion WebMovement of solute from higher concentration to lower concentration across a concentration gradient.

WebAug 8, 2024 · Graham's law can be understood by comparing two gases ( A and B) at the same temperature, meaning the gases have the same kinetic energy. The kinetic energy of a moving object is given by the equation K E = 1 2 m v 2 where m is mass and v is velocity. Setting the kinetic energies of the two gases equal to one another gives:
