Visualizing Energy Changes in Chemical Reactions through Reaction Profiles

The video discusses how diagrams of reaction profiles can be used to show the energy changes that occur during chemical reactions. It explains the concept of energy conservation in chemical reactions and how the transfer of energy to or from the surroundings affects the energy of the product and reactant molecules. The video then illustrates the different reaction profiles for exothermic and endothermic reactions and provides examples of each type of reaction and their uses, such as combustion, decomposition, neutralization, and sports injury packs.
