(a) Interpretation: Calculate the value of equilibrium constant for dissolution of AgBr which is a sparingly soluble solute with the help of given thermodynamic data. Concept introduction: Sparingly soluble salts form their respective ions in their solutions. The dissolution process is just opposite to the precipitation reaction. The standard free energy change can be calculated with the help of Gibb’s energy for the reactant and products. The mathematical expression of Gibb’s energy can be written as: ΔrG° = ΔrG°(product) - ΔrG°(reactant) K p or Kc are the equilibrium constants for the reaction which are ratio of gaseous and aqueous products and reactant molecules. The relation between equilibrium constant and Δ rG ° can be written as: ΔrG° = - 2 .303 RT log K Here: R = 8.314 J / mol .K T = temperature in Kelvin
