WebGraham's Law Calculator. R1 = Rate of effusion (or diffusion ) of the first gas ; R2 = Rate of effusion (or diffusion) of the second gas; M1 = Mass of the first gas; M2= Mass of the second gas. Graham's law states that the rate of effusion (or of diffusion ) of a gas is inversely proportional to the square root of it's molecular weight. WebOct 6, 2024 · Answer: The ratio of rate of effusion of chlorine gas and oxygen gas will be 0.671. Explanation: To calculate the rate of diffusion of gas, we use Graham's Law. This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

WebNov 14, 2024 · We are required to identify the gas that will diffuse at the slowest rate. In other words we are required to determine the heaviest gas. Looking at the molar mass of the gases given; Cl₂- 70.91 g/mol. H₂- 2.02 g/mol. He - 4.00 g/mol. Ne- 20.18 g/mol . Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among ... WebOct 6, 2024 · Answer: The ratio of rate of effusion of chlorine gas and oxygen gas will be 0.671.
