Which will diffuse through a membrane more rapidly, co or n2? assume that the samples contain only the most abundant isotopes of each element, 12c, 16o, and 14n?

Answer: Both will diffuse at the same rate

Step-by-step explanation:

According to Graham's law, the rate of diffusion is inversely proportional to the square root of the relative molecular mass of the gases. The two gases, carbon II oxide and nitrogen gas has the same relative molecular mass (28). This implies that they must diffuse at the same rate through an membrane.

I think the answer for the above question is none. The two gases will diffuse at the same rate; simply because they have the same molecular mass. N2 = 28 g and CO = 28 g. From the Graham's law, the rate of diffusion of a fixed mass of a gas is inversely proportional to the square root of its molecular mass. The heavier the gas is the lower the rate of diffusion and vicevarsa.
