B
Adding a reactant at equilibrium decreases the value of Kc, shifting the reaction to the left.
C
The equilibrium constant, Kc, remains unchanged regardless of the concentrations of reactants and products.
D
At equilibrium, the rates of the forward and reverse reactions are equal, but concentrations can still vary.
