Q.
Solubility of CO2 is ___________ higher than that of O2.
NTA AbhyasNTA Abhyas 2020Breathing and Exchange of Gases
Solution:
Rate of diffusion is affected by the following factors :
a. Concentration/pressure gradient.
b. Solubility of the gases (Solubility of $C O_{2}$ is 20-25 times higher than that of $O_{2}$ , so $C O_{2}$ can diffuse at a higher rate).
c. Thickness of the membranes (Diffusion membrane at the level of alveoli is having a thickness of less than 1 mm, so it favours the diffusion of gases).
