Is formation of silver chloride by the combination reaction of silver and chlorine a endothermic reaction?

Open in App

Solution

A decomposition reaction can be defined as a chemical reaction in which one reactant breaks into two or more products.
The general format is AB→A+B.
Photolytic decomposition: it is defined as a decomposition of a reaction that is activated by sunlight energy or breaking of reactant into its constituent chemical reaction by absorbing energy from photons.
For example: 2AgCl→2Ag+ $C l_{2}$ ( in presence of sunlight).
So, as we can see decomposition of silver chloride is an example of photolytic decomposition as it requires sunlight as energy to break the reactant into constituent elements.
Hence, the reaction is ENDOTHERMIC.
