Learning Goal: To understand how to calculate the equilibrium constants for chemical equations that can be produced by the addition of other chemical equations with known equilibrium constants. For a chemical reaction equation with the general form the equilibrium equation is given by Thus, for a chemical reaction equation with the general form the equilibrium equation is given by If the first two equations are added together such that then the equilibrium equation is given by or K3 aA + bB =cC + dD = K₁ = cC + dD=eE+fF K2 = [C] [D]d [A]ª[B]b [E] [F] [C]c[D]d aA +bB=eE+fF = [E] [F] [CD] [A]a[B]b [A]a[B] [E] [F] [C]c[D]d K3 = K₁ K₂ Thus, when a chemical equation is the sum of two chemical equations for which equilibrium constants are already known, the equilibrium constant for the reaction is the product of the equilibrium constants for the individual reactions. Keep in mind that equilibrium equations do not include expressions for any pure solids or liquids that may be involved in the…

Which of the following statements is (are) true? (Select all that apply.) If equilibrium constants for the chemical reaction N2(g) + O2(g) : = 2 NO(g) are K, = 1.1 x 103 and 3.6 x 103 at 2,200 K and 2,500 K, respectively, then the reaction is exothermic. If Q < K then the reactant concentrations will be decrease as the reaction proceeds to equilibrium. Concentration of the products equals the concentrations of the reactants. If the reaction, C(s) + 2H2(g) = CH4(g) is at equilibrium, adding solid carbon will cause the reaction to shift in the forward direction. None of these statements are true. O At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction.
