When the number of moles of reactants and products are equal in reversible reaction which parameter would not affect at fusion equilibrium?

Correct answer: B. Pressure

  • A. Temperature
  • B. Pressure
  • C. None of them
  • D. Catalyst

Explanation

When the number of moles of reactants and products is equal, changes in pressure do not affect the equilibrium position because there is no net change in volume. Temperature can affect equilibrium because it can alter the balance of endothermic and exothermic reactions. A Catalyst speeds up the rate of a reaction but does not change the equilibrium position.

About Chemical Equilibrium

Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
