• C) the equilibrium constant is increased for the reaction A + B ⇌ C if the concentration of A is increased
• D) an increase of temperature causes a decrease in the value of the equilibrium constant for an exothermic reaction
• E) when an equilibrium system is stressed, the system reacts to offset the stress
