Question

Starting with the definition of the rate of effusion and Graham’s findings relating rate and molar mass, one can derive Graham’s law equation, which relates the relative rates of effusion for two gases to their molecular masses.

Answer 1

Graham's law states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of the molar mass of the gas.

Step-by-step explanation:

Graham's law states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of the molar mass of the gas. This means that lighter gases will diffuse or effuse faster than heavier gases. The relationship between the rates of effusion of two gases is given by the square root of the ratio of their molar masses.

For example, if gas A has a molar mass of 16 g/mol and gas B has a molar mass of 32 g/mol, the rate of effusion of gas A will be twice as fast as gas B.
