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.
