Chem 2/ 5 Labs FS98 Postlab for Lab #404 LeChatelier's Principle (1) Write out the equilibrium-constant expression for the following (a) Ca(OH)2(s) <=> Ca 2+(aq) + 2OH-(aq) (b) N2(g) + 3 H2(g) <=> 2 NH3(g) (c) CaBr2(aq) + 2 KOH(aq) <=> Ca(OH)2(s) + 2 KBr(aq) (2) Will raising the temperature of an exothermic reaction affect the equilibrium constant for that reaction, or just the balance of products and reactants? Explain.
