Chemistry

In this lesson, we will learn how to use Le Chatelier’s principle to predict directions of change for equilibria in response to a stimulus.

Worksheet

Q1:

How does an increase in temperature affect the equilibrium constant for an exothermic reaction?

Q2:

Consider the exothermic reaction shown, which reaches equilibrium at 500 K and 10 bar. Which of the following actions would lead to a decrease in the amount of methanol in the equilibrium reaction mixture?

Q3:

Consider the following reaction. Suppose you wanted to shift the equilibrium position of the reaction in the direction that favors more dimer formation. Which of the following changes in reaction conditions would help achieve that goal?
