For a reversible reaction, if the concentrations of the reactants are doubled, at constant temperature the reaction will

Correct answer: D. Move towards the right.

  • A. Stand still
  • B. Slow down
  • C. Speed up in reverse direction
  • D. Move towards the right.

Explanation

According to Le Chatelier's Principle,If you increase the concentration of reactants, the equilibrium will shift in the direction that consumes reactants - i.e., the forward direction - to restore equilibrium.Move toward the right - because the system shifts forward to use up the excess reactants and re-establish equilibrium

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.
