Question

Following is the correct order of diffusion rate of oxygen, carbon dioxide and nitrogen from lungs to blood through the respiratory membrane (A) CO 2> O 2> N 2 (B) CO 2> N 2> O 2 (C) O 2> CO 2> N 2 (D) O 2> N 2> CO 2

Oxygen diffuses two times faster than nitrogen, while carbon-di-oxide diffuses 20 times faster than oxygen.

Q. Following is the correct order of diffusion rate of oxygen, carbon dioxide and nitrogen from lungs to blood through the respiratory membrane

$C O_{2} > O_{2} > N_{2}$

$C O_{2} > N_{2} > O_{2}$

$O_{2} > C O_{2} > N_{2}$

$O_{2} > N_{2} > C O_{2}$

Oxygen diffuses two times faster than nitrogen, while carbon-di-oxide diffuses $20$ times faster than oxygen.
