Why is a chemical equilibrium described as dynamic?
A) Because maximum randomness has been achieved.
Because the pressure and temperature do not change.
C) Because both reactants and products continue to form.
D) Because the concentrations of chemical species remain constant.
E) Because the reactant and product molecules are in constant motion.

c) both forward and reverse rnxs are going on
I would have to say D because : In a chemical reaction, chemical equilibrium is the state in which the concentrations of the reactants and products have no net change with time. Usually, this state results when the forward reaction proceeds at the same rate as the reverse reaction. The reaction rates of the forward and reverse reactions are generally not zero but, being equal, there are no net changes in the concentrations of the reactant and product. This process is called dynamic equilibrium.
Hope that helps you , Good luck.
i know this answer. this answer is because the concentrations of chemical species remain constant
