The movement of gas molecules from one place to the other along the concentration gradient is called diffusion.
When they are allowed to escape through a tiny hole under pressure, this phenomenon is called effusion.
Graham's law of diffusion (also known as Graham's law of effusion) states that the rate of effusion a gas is inversely proportional to the square root of its molar mass.
Rate of diffusion of gas = volume of gas diffusion / time taken
Thus, given statement is FALSE.
