In an exothermic reaction is heat considered a product or a reactant? What physical change would indicate that a reaction was exothermic? 2. 3. For the following equilibrium list 2 changes that will favor the formation of reactants? 3%(g) + N2(g) ââ 2NH3(g) -92 KJ/mol Lab 5. Equilibrium Constant Determination 1. What is the definition of the "equilibrium constant"? Write the equilibrium constant expression for the following reaction: Pb2+(aq) + 2ã(aq) ââ PbI2(s) 2. Consider the reaction studied in this lab: Suppose you knew the equilibrium concentration for Fe was 0.0027 M and for SCN was 0.0036 M. if the absorbance at the equilibrium concentration of FeSCN was 0.470, calculate Keq for this reaction. (pathlength is 1 cm and ε is 185 cm" Mr) (10)
