Solution
The correct answer is a. The rates of the forward and reverse reactions are equal. The concentrations of the reactants and products are constant.
When a chemical reaction reaches equilibrium, it means that the rate at which the reactants are being converted into products is the same as the rate at which the products are being converted back into reactants. This does not necessarily mean that the concentrations of the reactants and products are equal, but rather that they are constant – they are not changing over time. This is because the forward and reverse reactions are happening at the same rate, so the amounts of reactants and products remain stable.
