B) equilibrium will be established quickly if there is no disturbance in temperature or pressure.
C) when a disturbance occurs to a system at equilibrium,a new equilibrium constant will be established.
D) when a disturbance occurs to a system at equilibrium,the system will shift to minimize the disturbance.
