    Q:

    		 Chatelier's principle is used to predict what happens to a chemical equilibrium upon a change in conditions. Which of the following is NOT an example of a reaction that correctly readjusts itself to a change in conditions?
    		 

    A

    		 The amount of product increases if the concentration of a reactant increases.

    B

    		 Given a reversible exothermic reaction that produces ammonia, less ammonia is produced if the temperature is increased.

    C

    		 Given a reaction that produces ammonia, more ammonia is produced upon the addition of a catalyst.

    D

    		 Given a reaction that changes from 2 total gas moles of reactants to 1 total gas mole of product, the equilibrium shifts to the reactant side if the volume is increased.
