CO2 diffuses approximately 20 times faster across the alveolar-capillary membrane than O2 because of its much higher solubility in plasma .
Why is CO2 more soluble than O2 in blood?
First, carbon dioxide is more soluble in blood than oxygen. By continuing, I agree that I am at least 13 years old and have read and CO2 has the ability to react with water to form carbonic acid and this tends to increase its solubility in water . The solubility of CO2 in water is about 24 times that of O2.
Which gases would diffuse faster than carbon dioxide?
Molar mass CO2 is 44.01. Let carbon dioxide be gas # 2. Therefore, ammonia diffuses 1.61 faster than carbon dioxide. Empirical answer: the gas with the lesser molar mass will diffuse faster.
Does CO2 diffuse faster than h2?
The lighter the molecule, the faster will be the diffusion. In this case, Hydrogen has molecular mass of 2 while Carbon Dioxide has molecular mass of 44. So it is obvious that : Hydrogen will diffuse faster than Carbon Dioxide .
Which one of the gas diffuses fastest?
The rate of effusion for a gas is inversely proportional to the square-root of its molecular mass (Graham's Law). The gas with the lowest molecular weight will effuse the fastest. The lightest, and therefore fastest, gas is helium .
Do CO2 and O2 react?
O2 and CO2 do not react under ordinary conditions , owing to the thermodynamic stability of CO2 and the large activation energy required for multiple double-bond cleavage.
Is oxygen more soluble than carbon dioxide in blood?
Carbon dioxide is 20 times more soluble than oxygen ; it obeys Henry's law, which states that the number of molecules in solution is pro- portional to the partial pressure at the liquid surface. ... This corres- ponds to 0.5 ml kPa–1 carbon dioxide in 100 ml blood at 37 C.
Which diffuses faster liquid or gas?
Gases diffuse faster than liquids . This is because the particles of gases are much farther apart from one another as compared to the solids and liquids.
Which gas will diffuse faster CO2 or n2?
nitrogen because it has low relative molecular mass than oxygen. so because of low molecular mass it is lighter and diffuses faster.
Which gas diffuses faster hydrogen or oxygen?
Does hydrogen diffuse 4 times faster than oxygen? Answer: Hydrogen (H2) gas diffuses 4 times faster than oxygen (O2) gas. Explanation: According to Graham's law of diffusion, the rate of diffusion or movement of gas is inversely proportional to the square root of it's molecular weight.
Would Cl2 or CO2 diffuse more rapidly?
Answer: Out of four gases CI2, CO2 , CH4 ,N2 which of these gas would diffuse most rapidly and why. Out of Cl2, CO2, CH4 and N2 the gas which will diffuse more rapidly is CH4. This is because mass of CH4 is least and diffusion is inversely proportional to mass of gas i.e., lighter gases diffuses faster.
What is the fastest diffusion?
Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. Effusion refers to the movement of gas particles through a small hole. Graham's Law states that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Does ethane diffuse faster than methane?
1 The rate of diffusion of two gases, methane, CH4, and ethene, C2H4, is measured using the apparatus shown. Which gas diffuses faster and why? A ethene Ethene molecules are heavier and so move faster . ... C methane Methane molecules are lighter and so move faster.
Which gas carbon dioxide or Sulphur dioxide would diffuse faster?
as diffusion is inversely proportional to root of molecular mass of gas. hence,molar mass of so2 is more than co2 therefore, co2 gas diffuse more faster than so2 gas.
Which type of diffusion is very very slow?
The diffusion of a solid in another solid is a very slow process because the particles in solids can not move from their positions. the particles can show a little vibrations about their fixed position. due to lack of sufficient movements in particles of solids,the diffusion of solids in solids is a slow process.
How can you increase the density of a gas?
Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant , density increases. Conversely when temperature increases, with pressure constant, density decreases.
