Is cracking a decomposition reaction

WebThermal decomposition is a type of chemical reaction in which a compound breaks down into simpler substances due to the application of heat. In this process, a molecule is broken down into smaller molecules, atoms or ions, by absorbing thermal energy, which typically increases the rate of the reaction.
