Which of the following is NOT true at equilibrium? Options: 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.

Back

When K is larger than 1, what happens at equilibrium?

Back

There are more products than reactants when the reaction reached equilibrium.

Front

What are the two factors to look for when determining if the reaction is at equilibrium?

Back

Forward and reverse reaction rates are equal and concentration is constant
