What is Reactions & Energy?
Chemical reactions transform substances into new forms, releasing or absorbing energy. From burning fuel to photosynthesis, reactions drive the chemical world. Understanding reactions lets you predict what will happen when substances combine and why energy changes occur.
In this area, you'll explore types of reactions, energy changes, reaction rates, acids and bases, and energy conservation. These topics explain how chemistry actually happens—what drives change and what controls reaction behavior.
