Solution

Photodecomposition reaction:

  1. It takes place in the presence of light.
  2. In this type of reaction, the reactants absorb light and are broken down into their constituents elements.

Decomposition of Silver chloride:-

  1. When silver chloride(AgCl) is kept in presence of sunlight, the silver chloride compound absorbs the light.
  2. By absorbing this light it decomposes to form silver and chloride gas.
  3. The reaction is:

2AgCl(s)Silverchloridelight2Ag(s)Silver+Cl2(g)Chlorinegas

Therefore, an example of a reaction that requires light is the decomposition of silver chloride (AgCl) in presence of light:

2AgCl(s)Silverchloridelight2Ag(s)Silver+Cl2(g)Chlorinegas
