Examine the following chemical equation:

                                     2Cl₂(g) + 2H₂O(g) + Heat   <--->     4HCl(g)   +   O₂(g)       

  If the temperature of the system is increased in which direction will the system shift to reestablish equilibrium?  

Examine the following chemical equation:

                                     2Cl₂(g) + 2H₂O(g) + Heat   <--->     4HCl(g)   +   O₂(g)       

 If O₂ is added to the system, in what direction will the reaction shift to reestablish equilibrium? 

In the equilibrium reaction: A(g) + 2B(g) + Heat <---> AB₂(g), under which stress condition will the reaction shift right towards making products?

For a given exothermic reaction at equilibrium, how will lowering the temperature affect the reaction direction?                      Reaction:     A + B --> C + Heat Energy

Which of the following will increase the rate of a reaction?
