The diffusion capacity of $CO_2$ is much higher than that of $O_2$.

Vedclass · Answer

(A) The diffusion capacity of a gas across the alveolar membrane depends on its solubility and the thickness of the membrane.According to Fick's law of diffusion,the rate of diffusion is directly proportional to the solubility of the gas.The solubility of $CO_2$ is $20-25$ times higher than that of $O_2$ in the blood.Therefore,the amount of $CO_2$ that can diffuse through the diffusion membrane per unit partial pressure difference is much higher than that of $O_2$.
