eversible reactions

• • A reversible reaction is a chemical reaction that can proceed in both forward and backward directions.
• • The reactants can form the products, which in turn can react to produce the original reactants.
• • A reaction is shown to be reversible by the presence of a double-headed arrow in the chemical equation.
• Characteristics of Reversible Reactions

  • Equilibrium is reached in a closed system where the concentrations of reactants and products remain stable over time.
  • At equilibrium, the forward and backward reactions continue to happen, but there is no overall change as the rates of these reactions are equal.
  • The position of equilibrium can be on the side of the reactants (left) or products (right) and it indicates the concentrations of substances in the balanced system
• • A dynamic equilibrium occurs in a closed system when the rate of the forward reaction is equal to the rate of the reverse reaction.
