Difference in the rates of diffusion of gases

Vedclass · Answer

(A) The marsh gas detector used by miners works on the principle of the difference in the rates of diffusion of gases.Graham's law of diffusion states that the rate of diffusion of a gas is inversely proportional to the square root of its molar mass $(Rate \propto \frac{1}{\sqrt{M}})$.Marsh gas,primarily composed of methane $(CH_4)$,diffuses at a different rate compared to air. This difference in diffusion rates allows the detector to identify the presence of methane in the mine atmosphere,ensuring safety for the miners.
