Which of the following happens when a reaction reaches dynamic equilibrium in a closed system?
A) The concentrations of the reactants and products increase.
B) The concentrations of the reactants and products remain constant
C) The rate of the forward reaction is faster than the rate of the reverse reaction.
D) The rate of the forward reaction is slower than the rate of the reverse reaction
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction, and thus the concentrations of the reactants and products must be constant.
