Energy in Reactions
Understanding how energy levels shift during chemical reactions reveals the difference between exothermic and endothermic processes. When reactants have higher energy than products, heat is released, while the opposite scenario absorbs energy, cooling the surroundings. The concept of collision theory further explains that for reactions to occur, particles must collide, with their motion influenced by the state of matter.In this clip
