Gresham's Law actually doesn't relate to gas diffusion; it's about currency. However, the statement that matches the concept of gas diffusion rates as described by Graham's law (likely what the question intended to reference) is that the rate of diffusion is inversely proportional to the square root of the mass of the molecules.
