Which of the following is NOT true at equilibrium?

Question

The forward and reverse reactions proceed at the same rate.
The concentrations of reactants and products do not change.
The concentration of the reactants is equal to the concentration of the products.
The forward and reverse reactions continue to occur.

Answer 1

This appears to be a chemistry question rather than a history question, but the answer is: The concentration of the reactants is equal to the concentration of the products is NOT true at equilibrium. At equilibrium, the forward and reverse reactions proceed at the same rate, the concentrations of reactants and products do not change, and the forward and reverse reactions continue to occur, but the concentrations of reactants and products are not necessarily equal.
