AP Chemistry
7.9 Introduction to Le Châtelier’s Principle
A mixture of \(\text{N}_2\text{O}_4\text{(g)}\) and \(\text{NO}_2\text{(g)}\) is at equilibrium inside a rigid cylinder fitted with a movable piston at a constant temperature, as represented by the equation below:
\[ \text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\,\text{NO}_2\text{(g)} \]
The piston is pushed inward to decrease the volume of the container at constant temperature. Which of the following best predicts the direction the reaction will shift to re-establish equilibrium, and provides the correct justification?
\[ \text{N}_2\text{O}_4\text{(g)} \rightleftharpoons 2\,\text{NO}_2\text{(g)} \]
The piston is pushed inward to decrease the volume of the container at constant temperature. Which of the following best predicts the direction the reaction will shift to re-establish equilibrium, and provides the correct justification?
