Gibbs free energy is minimum at equilibrium. 3 Quantitative Aspects of Equilibrium Constants Quantitative Aspects of Equilibrium Constants Magnitude of K and Extent of Reaction Estimating Equilibrium Constants If we know the concentrations of species in a reaction mixture at equilibrium we can calculate the equilibrium constant at the temperature equilibrium, we can calculate the equilibrium constant at the temperature of measurement by substituting the concentrations into the reaction quotient. Equilibrium Constant K at 1000 K: Q SO3 2 0.9252 2.8 102 K SO2 2 O2 0.0752 0.54 Quantitative Aspects of Equilibrium Constants Reaction Equations and Equilibrium Constants Calculating Equilibrium Concentrations If we know the equilibrium constant of a reaction at the temperature of a reaction mixture and the starting concentrations of species, we can calculate the equilibrium concentrations of the species. Doubling the Reaction Equation An equilibrium constant is specific for the chemical equation on which it is based. If the co...
