  • The Rate of formation of products depends on the concentration of reactants or the forward reaction increases on increasing the rate of the concentration.
  • There is no effect on the equilibrium rate when the concentration of reactants and products is constant.
  • Forward reaction slows down when the reactant concentration is decreased.
  • On increasing the amount or concentration of reactant the chemical  equilibrium shifts towards formation of more products.
  • Hence, the forward reaction speeds up.
