Energy diagrams are graphical representations that illustrate the energy changes during a chemical reaction. They show the potential energy of a system as it progresses from reactants to products.
This is the minimum amount of energy required for a chemical reaction to occur. It's like needing enough speed to get your roller coaster over its first big hill.
This is the highest-energy state of a reaction, where old bonds are breaking and new ones forming. It's like reaching the topmost point on your roller coaster ride before plunging down towards new adventures.
A type of chemical reaction that releases heat into its surroundings. If our rollercoaster ends lower than it started, we've gone downhill - this is similar to an exothermic reaction where overall, energy has been released.
