Class 10 Chemistry Chapter 9 Short Questions

  • Reversible reactions are those in which products recombine to form reactants. These reactions are never complete. They proceed in both ways; i.e., forward and reverse.
  • The dynamic equilibrium state is one at which forward and reverse reactions proceed at equal rates but in opposite directions so that the overall reaction does not stop.
  • Equilibrium constant Kc is a ratio of the product of the concentration of products raised to the power of coefficients to the product of the concentration of reactants raised to the power of coefficients as expressed in the balanced chemical equation.
  • The equilibrium constant has no units when the number of moles of reactants and products are the same.
  • By knowing the value of equilibrium constants, the extent of a reaction can be predicted.
  • Reactions having large Kcvalue, proceed almost to completion.
  • Reactions having a small magnitude of Kc indicate that an equilibrium state has been established by consuming a small amount of reactants. Therefore, they never go to completion.
  • Reactions having moderate magnitude have comparable amounts of reactants and products at equilibrium state.
