For a chemical reaction to occur, activation energy is required. Using the activation energy, reactants form products by breaking bonds which require energy. This type of reaction is an endothermic reaction. When products are formed, bonds are formed back by releasing energy. This type of reaction is an exothermic reaction. When activation energy is used for a reaction, a catalyst is not required. Adding a catalyst to the reaction causes the rate of reaction to increase.

A chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires a minimum amount of energy.

  • A reactant is a starting substance in a chemical reaction, whereas products are formed at the end of the reaction.

  • The rate of reaction is the velocity of the chemical reaction.

  • Activation energy refers to the minimum amount of energy required to activate reactants and thus start a chemical reaction.

  • The chemical reactions store/release energy by destroying/building chemical bonds between atoms/molecules.

  • Exothermic reactions release energy when the bonds are formed; whereas endothermic reactions consume energy.

In conclusion, a chemical reaction is a process where two or more reactants are converted to one or more products at a given rate, which requires energy. These reactions can be exothermic processes or endothermic processes.
