Dalton’s law of partial pressure

Dalton’s law of partial pressure. At constant volume and temperature, the total pressure of a mixture of gases is the sum of the partial pressures of all the gases present. P total = P 1 + P 2 + P 3 …. Example.

  1. Dalton’s law of partial pressure • At constant volume and temperature, the total pressure of a mixture of gases is the sum of the partial pressures of all the gases present. • Ptotal = P1 + P2 + P3…

  2. Example • What is the partial pressure of O2 (PO2) at 1 atm if PN2 = 593.4 mm Hg, PCO2 = 0.3 mm Hg, and Pothers = 7.1 mm Hg?

  3. Determine the total pressure of a gas mixture that contains O2, N2, and He if PO2 = 150 mmHg, PN2 = 350 mm Hg, PHe = 200 mm Hg.

  4. Mole Fraction and Partial Pressures • Mole Fraction – a dimensionless quantity that expresses the ratio of moles of one component to moles of all components present. • Pa = aPt , where a is the mole fraction: mol A = X Total Moles
