B) the forward reaction is only occurring. FALSE. The forward reaction and the reverse reaction occur at the same rate.
C) the concentrations found at equilibrium are different if a system approaches equilibrium from different directions. FALSE. The equilibrium is the same regardless of the direction from which it comes.
D) the concentration of reactants and products remains constant. TRUE.
