This edition: Rates & Equilibrium: Controlling Reactions
This lesson adds additional detail to what you already learned regarding what factors must be present for reactions to occur. In earlier lessons, you learned why certain substances react while others do not. In this lesson, you learn how successful reactions occur and why they occur at different rates. The factors (or variables) you learn about in this lesson can be applied to all of the millions of reactions that are occurring around you right now. The video explains these factors using the air we breathe as an example and the textbook provides many other real-world applications of this information. Think about the world around you as you review this lesson.
