One of the following equilibria is not affected by the change in the volume of the flask:

Correct answer: B. Option B

  • A. Option A
  • B. Option B
  • C. Option C
  • D. Option D

Explanation

This reaction involves a change in the number of moles of gas particles on both sides of the equation, but the total number of moles remains the same, so the equilibrium is not affected by changes in volume.

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.
