Question

Decomposition of Silver chloride reaction is an example of?

Answer 1

Decomposition reaction:

• Decomposition reaction can be defined as a chemical reaction in which one reactant breaks into two or more products.
• It is mostly used for the extraction of metals from their ores. i,e Zinc can be obtained from Calamine ore by subjecting it to a decomposition reaction.

Photolytic decomposition:

• Photolytic decomposition is known as a decomposition reaction that is activated by sunlight energy or breaking of reactant into its constituent chemical reaction by absorbing energy from photons.
• For example, The decomposition of an Ozone molecule into Dioxygen and an Oxygen radical, can be shown as the chemical reaction given as:

$\underset{\left(\mathrm{Ozone}\right)}{{\mathrm{O}}_3\left(\mathrm{g}\right)}+\mathrm{h\nu }\to \underset{\left(\mathrm{Dioxygen}\right)}{{\mathrm{O}}_2\left(\mathrm{g}\right)}+\underset{\left(\mathrm{Oxygen}\mathrm{radical}\right)}{{\mathrm{O}}^{.}}$

Decomposition of Silver chloride reaction:

• The decomposition of Silver chloride undergoes in the example of photolytic decomposition as it requires sunlight as the energy, to break the reactant into constituent elements.
• For which the reaction can be given as :

$\underset{\left(\mathrm{Silver}\mathrm{chloride}\right)}{2\mathrm{AgCl}\left(\mathrm{aq}\right)}\to \underset{\left(\mathrm{Silver}\right)}{2\mathrm{Ag}\left(\mathrm{s}\right)}+\underset{\left(\mathrm{Chlorine}\right)}{\mathrm{C}{\mathrm{l}}_2\left(\mathrm{g}\right)}$( in presence of sunlight).

Hence, decomposition of Silver chloride reaction is an example of photolytic decomposition.
