What is Le Chatelier Principle about?
Correct answer: C. Equilibrium Mixture
- A. Reaction Mixture
- B. Reactants
- C. Equilibrium Mixture
- D. Products
Explanation
Option C is correct since Le Chatelier's principle is an observation about the chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system to achieve a new equilibrium state.

About Le Chatelier's Principle
Le Chatelier's principle predicts how an equilibrium responds when concentration, pressure or temperature changes. Questions apply it to reversible reactions, identify the direction of shift and distinguish genuine equilibrium changes from the effect of a catalyst, which changes the rate of reaching equilibrium but not its position.
