1.   What are the chemical hazards of NaOH, NaHSO4 and AgNO3?








2.  How will increasing the temperature affect an endothermic reaction?
 (Shift L or Shift R, no effect)  Explain.





For the reaction:     N2(g) + 3H2(g) <==> 2NH3(g)
3.  What is the equilibrium constant expression for this reaction?





4.  What will be the effect of decreasing overall pressure on this reaction?
(Shift L, Shift R, no change)  Explain.







5.  If H2(g) is removed from the mixture at equilibrium, what will be the effect?
(Shift L, Shift R, no change) Explain.
