What is not true about the Le -Chatelier's principle?
Correct answer: B. Allow to predict the change in reaction rate on system at equilibrium
- A. Allow to predict the change in concentration on system at equilibrium
- B. Allow to predict the change in reaction rate on system at equilibrium
- C. Allow to predict the change in pressure on system at equilibrium
- D. Allow to predict the change in temperature on system at equilibrium
Explanation
Le Chatelier's principle helps predict the effect of changes in concentration, temperature, and pressure on a system at equilibrium. However, it doesn't predict the actual change in pressure itself; rather, it explains how pressure changes can affect 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.
