Chemistry

In each of the following questions, identify which way (to the left or to the right) does equilibrium shift to relieve the described applied stress:

5)  Consider the following reversible reaction at equilibrium: CO(g) + Cl2(g) COCl2(g). If chlorine gas is added to the equilibrium system, how is the stress relieved?

6)  Consider the following reversible reaction at equilibrium: C6H12O6 (aq) + 6 O2(g) 6 CO2(g) + 6 H2O(l).  If oxygen gas is removed from the equilibrium reaction vessel, how is the stress relieved?

7)  Consider the following reversible reaction at equilibrium: C6H12O6 (aq) + 6 O2(g) 6 CO2(g) + 6 H2O(l).  Given that this reaction is exothermic, if heat is added to the equilibrium system, how is the stress relieved?
