Drag the appropriate items to their respective bins. View Available Hint(s) The forward and reverse reactions proceed at the same rate. Chemical equilibrium is a dynamic state. The ratio of products to reactants is not stable. Reset Help The state of chemical equilibrium will remain the same unless reactants or products escape or are introduced into the system. This will disturb the equilibrium. The concentration of products is increasing, and the concentration of reactants is decreasing. The ratio of products to reactants does not change. The rate at which products form from reactants is equal to the rate at which reactants form from products. The concentrations of reactants and products are stable and cease to change. The reaction has reached equilibrium. The rate of the forward reaction is greater than the rate of the reverse reaction.
