Question

In which of the following pairs the gaseous species diffuse through a porous plug along with the same
rate of diffusion​

Answer 1

Answer:

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

The molecular mass of NO and C2 H 6

is the same. Hence, both diffuse with the same rate of diffusion.
