Compared to $O_2$,the diffusion rate of $CO_2$ through the diffusion membrane per unit difference in partial pressure is much higher. Explain.

(N/A) The solubility of $CO_2$ is $20-25$ times higher than that of $O_2$. Due to this high solubility,the amount of $CO_2$ that diffuses across the diffusion membrane per unit difference in partial pressure is significantly greater than that of $O_2$.
