Consider the reaction:  

 AC(g)+2B(g)AB2\displaystyle {A}{C}_{{{\left({g}\right)}}}+{2}{B}_{{{\left({g}\right)}}}\leftrightarrow{A}{B}_{{2}} (g)  +C(g)\displaystyle +{C}_{{{\left({g}\right)}}}  ΔH=+56.9kJ\displaystyle \Delta{H}=+{56.9}{k}{J} 

The system is sitting at equilibrium.  Describe what will happen when each of the following stresses are applied.

 

Additional AC is added to the reaction vessel.
C is selectively removed from the reaction vessel.
