Compared to O(2) diffusion rate of CO(2)...

Compared to `O_(2)` diffusion rate of `CO_(2)` through the diffusion membrane per unit difference in partial pressure is much higher. Explain.

Text Solution

Verified by Experts

Diffusion rate of a gas depends upon its solubility in water. Because `CO_(2)` is about 20-25 times more soluble in water than `O_(2)` so the diffusion rate of `CO_(2)` through the diffusion membrane per unit difference in partial pressure in much higher than that of `O_(2)`.

Assertion :- The amount of CO_(20 that can diffuse through the diffusion membrane per unit differnece in partial pressure is much higher compared to that of O_(2) . Reason :- The solubility of CO_(20 is 20-25 times higher than that of O_(20 solubility.

Partial pressure of CO_(2) is higher :-

Both N_(2)O and CO_(2) have similar rates of diffusion under same conditions of temperature and pressure. Explain

Assertion: The diffusion of carbon dioxide is 20 times faster then oxygen. Reason: It is due to difference in partial pressure as well as solubility of diffusing gases .

N_(2)O and CO_(2) have the same rate of diffusion under same conditions of temperature and pressure. Why ?
