Learning Goal:To understand how to calculate the equilibrium constants for chemical equations that can be produced by the addition of other chemicalequations with known equilibrium constants.For a chemical reaction equation with the general formthe equilibrium equation is given byThus, for a chemical reaction equation with the general formthe equilibrium equation is given byIf the first two equations are added together such thatthen the equilibrium equation is given byorK3aA + bB =cC + dD=K₁ =cC + dD=eE+fFK2 =[C] [D]d[A]ª[B]b[E] [F][C]c[D]daA +bB=eE+fF=[E] [F] [CD][A]a[B]b [A]a[B][E] [F][C]c[D]dK3 = K₁ K₂Thus, when a chemical equation is the sum of two chemical equations for which equilibrium constants are already known, the equilibriumconstant for the reaction is the product of the equilibrium constants for the individual reactions. Keep in mind that equilibrium equations do notinclude expressions for any pure solids or liquids that may be involved in the reaction. ▼ Part AGiven the two reactions1.
