Unformatted text preview: the chemical equilibrium constant to the enthalpy of reaction. Establish the phase equilibrium for nonreacting systems in terms of the specific Gibbs function of the phases of a pure substance. Apply the Gibbs phase rule to determine the number of independent variables associated with a multicomponent, multiphase system. Apply Henry's law and Raoult's law for gases dissolved in liquids. | 793 794 | Thermodynamics CO2 CO O2 CO CO O2 CO2 O2 CO2 161 CRITERION FOR CHEMICAL EQUILIBRIUM Consider a reaction chamber that contains a mixture of CO, O2, and CO2 at a specified temperature and pressure. Let us try to predict what will happen in this chamber (Fig. 161). Probably the first thing that comes to mind is a chemical reaction between CO and O2 to form more CO2: CO 1 2 O2 FIGURE 161 A reaction chamber that contains a mixture of CO2, CO, and O2 at a specified temperature and pressure.
