According to the modern view of chemical reactions, b A great many common reactions are exothermic. Some reactions give off energy, some absorb it, but all of them use it. A catalyst is a chemical substance that speeds up chemical reactions by lowering the activation What energy changes happen during reactions? During a chemical reaction, heat energy can be given out or taken in by the chemicals. Endothermic reactions take in energy and the temperature of the surroundings A reaction profile is similar to an energy level diagram, but it includes the activation energy – the minimum energy that particles needed for a reaction to occur. Effective collisions Energy plays a crucial role in chemical reactions as it's needed to break the bonds in the reactants and form new bonds in the products.
