Dalton's law
Because gasses flow from areas of high pressure to areas of low pressure, atmospheric air has higher partial pressure of oxygen than alveolar air (PO2= 159mm Hg compared to PAO2= 100mm Hg). Similarly, atmospheric air has a much lower partial pressure for carbon dioxide compared to alveolar air (PCO2= 11.45atm)
Explanation:
- For the partial pressure of carbon dioxide
- we multiply 0.2 mol by our constant of 0.0821 and our temperature of 310 degrees K.
- then divide by 2 liters:
- 0.2 * 0.0821 * 310/2 = 2.54 atm, approximately.
- We now add these pressures to find the total pressure.
- Ptotal = 5.09 + 3.82 + 2.54, or 11.45 atm, approximately.
Asseration:
- Real gases do not obey Dalton's law of partial pressures. It is because these gases do not behave ideally and violate some of the rules of the kinetic theory of gases. Real gases behave ideally only under circumstances where the pressure is low and the temperature is high
- Carbon Dioxide (Co2) is a carbon atom covalently bounded to 2 oxygen atoms. It's colorless so ... So to answer your question, yes it's a real gas
