The equilibrium constant of a reaction is 300. If the volume of the reaction flask is tripled, the equilibrium constant is:

Correct answer: A. 300

  • A. 300
  • B. 900
  • C. 600
  • D. 100

Explanation

Equilibrium constant depends only on temperature for a given reaction.Changing volume, pressure, or concentration will shift the position of equilibrium (Le Chatelier's Principle) but will not change the numerical value of Keq unless temperature changes.

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.
