Final answer:
Chemical equilibrium occurs when the rates of the forward and reverse reactions are equal. The concentrations of reactants and products are constant at equilibrium, but not necessarily equal. A reaction quotient (Q) larger than the equilibrium constant (K) indicates that the reaction will favor the production of more products.
Step-by-step explanation:
Chemical equilibrium occurs when the rate of the forward reaction equals the rate of the reverse reaction. At equilibrium, the concentrations of reactants and products are constant, but it does not mean they are equal. The equilibrium constant for the forward reaction is equal to the equilibrium constant for the reverse reaction. A reaction quotient (Q) larger than the equilibrium constant (K) means that the reaction will favor the production of more products.
