Which is a proper description of chemical equilibrium?

A. The frequencies of reactant and product collisions are identical.
B. The concentrations of products and reactants are identical.
C. The velocities of product and reactant molecules are identical.
D. Reactant molecules are forming products as fast as product molecules are reacting to form reactants.
E. The numbers of moles of reactants and products are equal.

d) because both reactions are occurring at the same rate. They are not equal but their concentrations are constant.

The correct answer to describe chemical equilibrium is D: Reactant molecules are forming products as fast as product molecules are reacting to form reactants. At equilibrium, the forward and reverse reactions occur at equal rates, resulting in constant concentrations of reactants and products. This means that there is no net change in the amounts of reactants and products over time, even though the reactions continue to occur.
