The following reactions have the indicated equilibrium constants at a particular temperature: n2(g) + o2(g) ⇌ 2no(g) kc = 4.3 × 10−25 2no(g) + o2(g) ⇌ 2no2(g) kc = 6.4 × 109 determine the values of the equilibrium constants for the following equations at the same temperature: (a) 4no(g) ⇌ n2(g) + 2no2(g)

Infants born with severe respiratory problems are sometimes given liquid ventilation: they breathe a liquid that can dissolve more oxygen than air can hold. one of these liquids is a fluorinated compound, cf3(cf2)7br. the solubility of oxygen in this liquid is 66 mlo2 per 100 ml liquid. in contrast, air is 21 % oxygen by volume. calculate the moles of o2 present in an infant's lungs (volume: 12 ml ) if the infant takes a full breath of air. assume a pressure of 1 atm in the lungs.
