At dynamic equilibrium, the forward and backward reaction rates are equal.
Equilibrium can only be achieved when there is varying pressure dependent on the system with gases.
Constant temperature is not required for equilibrium because pressure and reaction rates are the only values that matter.
A change in color or pH cannot occur for equilibrium to happen.
Le Chatelier’s Principle states that a system will always shift to balancing out or counteracting the effect of changes in temperature, pressure, or concentration.
