1.  If a reactant is added to a reaction atequilibrium, which way will the reaction shift to re-establishequilibrium (use forward or backward)? Why?
2.  If a reaction is endothermic, is heat a reactantor a product?
3.  For an endothermic reaction, if heat is added,which way will the reaction shift to re-establish equilibrium (useforward or backward)? Explain your reasoning.
4.  A reaction has initial concentration of 0.330 M Fe3+and 0.210 M SCN- At equilibrium, the concentration of FeSCN2+ is0.150 M.
A) What is the concentration of the Fe3+ at equilibrium?
B) What is the concentration of the SCN- at equilibrium?
5.  For the equilibrium in question 4, what is thevalue of the equilibrium constant?
