Le Chatelier's Principle: Part 2

The video explains how a system at equilibrium responds to temperature changes, guided by Le Chatelier's principle. It discusses the energetics of reactions, highlighting that an increase in temperature favors endothermic reactions, while a decrease favors exothermic ones. The video uses the example of nitrogen dioxide dimerization to illustrate color changes with temperature variations. It also clarifies that catalysts speed up reactions but do not alter equilibrium positions. The video concludes by summarizing these concepts.

What does Le Chatelier's principle state about a chemical system at equilibrium when it is stressed?

How does an increase in temperature affect the direction of a reaction that is exothermic?

What observations can be made when the temperature of a system at equilibrium is decreased?

What happens to the production of nitrogen dioxide and dinitrogen tetroxide when the temperature is increased?

Explain the effect of adding a catalyst to a chemical reaction at equilibrium.
