A chemical reaction involves the interaction of atoms or molecules to form a new compounds. For a chemical reaction to occur, different atoms or molecules must move close enough for the-outer-shell electrons to interact. The terms reaction rate describes how quickly a chemical reaction occurs under given circumtanses, such as at a certain temperature or under particular light conditions.
Because many reactions occur extremely slowly, scientists sometimes add substances called catalysts to help speed the process. A catalyst reduces the activation energy required to initiate and sustain a reaction. The catalyst itself is never changed by the reaction.
The energy generated by atoms or molecules moving close together is called kinetic energy. Also The atoms or molecules must collide with sufficient kinetic energy to overcome the repelling forces to the electrons surrounding the nucleus of the atoms involved. The total amount of kinetic energy needed to achieve successful collision and reaction is called the activation energy.
