Which of the following explains higher rate of diffusion for $\mathrm{CO}_{2}$ than $\mathrm{O}_{2}$

Question

Which of the following explains higher rate of diffusion for $\mathrm{CO}_{2}$ than $\mathrm{O}_{2}$ ?\

Professor PC Thomas Classes · Answer

(a) : The solubility of $\mathrm{CO}_{2}$ is 20-25 times higher compared to $\mathrm{O}_{2}$. Thus, the amount of $\mathrm{CO}_{2}$ that can diffuse through the diffusion membrane per unit difference in partial pressure is higher than $\mathrm{O}_{2}$.
