Answer :
Answer:
Explanation:Certainly! Here are seven examples of photolytic decomposition reactions:
1. **Photodecomposition of hydrogen peroxide:**
\[ 2H_2O_2 \xrightarrow{\text{light}} 2H_2O + O_2 \]
Hydrogen peroxide breaks down into water and oxygen gas when exposed to light.
2. **Photolysis of water:**
\[ 2H_2O \xrightarrow{\text{light}} 2H_2 + O_2 \]
Water molecules decompose into hydrogen gas and oxygen gas under the influence of light.
3. **Photodecomposition of silver bromide:**
\[ 2AgBr \xrightarrow{\text{light}} 2Ag + Br_2 \]
Silver bromide decomposes into silver metal and bromine gas when exposed to light.
4. **Photolysis of hydrogen chloride:**
\[ 2HCl \xrightarrow{\text{light}} H_2 + Cl_2 \]
Hydrogen chloride gas decomposes into hydrogen gas and chlorine gas under light.
5. **Photodecomposition of ozone:**
\[ 2O_3 \xrightarrow{\text{light}} 3O_2 \]
Ozone molecules break down into oxygen molecules (O2) when exposed to ultraviolet light.
6. **Photodecomposition of ammonium chloride:**
\[ NH_4Cl \xrightarrow{\text{light}} NH_3 + HCl \]
Ammonium chloride decomposes into ammonia gas and hydrogen chloride gas under light.
7. **Photodecomposition of potassium chlorate:**
\[ 2KClO_3 \xrightarrow{\text{light}} 2KCl + 3O_2 \]
Potassium chlorate breaks down into potassium chloride and oxygen gas when exposed to light.
These examples demonstrate various substances undergoing photolytic decomposition reactions where the absorption of light energy initiates or accelerates the breakdown of the compound into simpler substances.
