Question

Decomposition of silver chloride is an example of?

Answer 1

Hint: There are so many chemical reactions we study in chemistry subject to know the behavior of chemical reactions like: combination reaction, decomposition reaction, displacement reaction, double displacement reaction, combustion reaction etc.

Complete answer:
Let’s first understand about decomposition reaction and their different types:
Decomposition reaction can be defined as a chemical reaction in which one reactant breaks into two or more products. General format is ($AB\to A+B)$.
It is used for the extraction of metals from their ores. For example: zinc can be obtained from calamine ore by subjecting it to a decomposition reaction and sodium can be obtained from sodium chloride ($NaCl)$.
Different types of decomposition reaction:
Thermal decomposition: it is defined as a decomposition of a reaction which is activated by thermal energy. In this reaction we supply energy to the reactant in the form of heat. These types of reactions are generally endothermic (i.e., we have to supply heat energy) as we want to break the chemical bond to separate the chemical elements. For example: $CaC{{O}_{3}}\to CaO+C{{O}_{2}}$.
Electrolytic decomposition: it is defined as a decomposition of a reaction which the activation energy for decomposition is provided in the form of electrical energy. For example: electrolysis of water ($2{{H}_{2}}O\to 2{{H}_{2}}+{{O}_{2}}$).
Photolytic decomposition: it is defined as a decomposition of a reaction which is activated by sunlight energy or breaking of reactant into its constituent chemical reaction by absorbing energy from photons. For example: $2AgCl\to 2Ag+C{{l}_{2}}$( in presence of sunlight).
So, as we can see decomposition of silver chloride is an example of photolytic decomposition as it requires sunlight as an energy to break the reactant into constituent elements.

Note:
We have to remember the meaning of decomposition reaction types of decomposition reactions so that we can identify which type of decomposition reaction is it.
