WebA photodecomposition reaction is a type of decomposition reaction in which the reactant is broken down to its constituents by absorbing energy from photons. An example of a photo decomposition reaction is the decomposition of ozone into dioxygen and an oxygen radical, as represented by the chemical equation provided below. O3 + hν → O2 + O. WebA strongly exothermic reaction will usually also be exergonic because ΔH⚬ makes a major contribution to ΔG⚬. Most of the spectacular chemical reactions that are demonstrated in …
