The solubility of $CO_2$ is ________ times higher than that of $O_2$ across the diffusion membrane.

  1. 2-5
  2. 10-15
  3. 20-25
  4. 50-100
Show answer and explanation

Correct answer: 20-25

As the solubility of $CO_2$ is 20-25 times higher than that of $O_2$, the amount of $CO_2$ that can diffuse through the diffusion membrane per unit difference in partial pressure is much higher compared to that of $O_2$.
