Investigating Chemical Reactions: Energy and Chemical Reactions

The video tutorial explains how energy is involved in chemical reactions, either being absorbed or released. It distinguishes between exothermic reactions, where energy and often light are released, and endothermic reactions, where energy is absorbed. The video also discusses the varying rates of chemical reactions, influenced by factors such as reactant concentration, temperature, and surface area.
