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.
