6. When heat is added to a system at equilibrium and the reaction shifts to the left, which statement is correct with respect to the reactions? * O It is an endothermic reaction. O It is an exothermic reaction. O It can be either endothermic or exothermic in the direction written. Nothing can be concluded with respect to the reaction being endothermic or exothermic. O The reaction has a heat term on each side of the reaction.

7. A system at equilibrium has more of a reactant gas injected into the
container. Which statement is most correct with respect to the reaction
after the injection. *
A new equilibrium position is established with a new Keq value that is larger than the
original Keq.
A new equilibrium position is established with a new Keq value that is smaller than
the original Keq.
A new Keg now exists and must be experimentally determined.
A new equilibrium position is established with the same Keq as the original system.
The original equilibrium position is re-established with a slightly larger Keq value.
