Energy Profile Diagrams: To show the activation energy of a reaction, energy profile diagrams are used. This diagram is a way of representing the energy changes that occur during a chemical reaction. The energy difference between the products and reactants...
Exothermic and Endothermic Changes: An exothermic reaction is one where energy (heat) is given out causing a temperature rise in the surroundings. The temperature of the reaction mixture rises. The container feels hot. Examples of exothermic reactions include:...
Making and Breaking Bonds: An exothermic change occurs when chemical bonds are made. An endothermic change occurs when chemical bonds are broken. The overall energy change of a reaction is the difference between the energy given out when bonds are made and...
Activation Energy: All reactions need energy in order to get started, weather it is an endothermic reaction or an exothermic one. The minimum energy that reacting particles must possess in order for a chemical reaction to occur is called the activation energy,...
