Which of the following reaction requires light?a)Electrolytic decomposition reactionsb)Photolytic decomposition reactionsc)Combination reactionsd)Thermolytic decomposition reactionsCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Photolytic Decomposition Reaction is defined as the reaction in which a reactant decomposes into two or more products in the presence of sunlight.

Ex:- 2AgCl → Ag2 + Cl2.

Photo means light. Hence, Option b is correct !!!

Answer

Photolytic decomposition reactin

Answer

'B'

Answer

PHOTO MEANS LIGHT WHICG MEANS LIGHT IS NEEDED FOR THIS REACTION

Answer

B is correct

Answer

Photolytic decomposition reactions require light.

Explanation:
Photolytic decomposition reactions are chemical reactions that involve the breaking of chemical bonds using light energy. In these reactions, light acts as a catalyst to provide the energy needed to break the bonds. The energy from the light is absorbed by the reactant molecules, causing them to become excited and undergo a chemical change.

Example:
One example of a photolytic decomposition reaction is the breakdown of hydrogen peroxide (H2O2) into water (H2O) and oxygen (O2) when exposed to light. The reaction can be represented as follows:
2H2O2 (light) → 2H2O + O2

Importance of Light:
Light is required for the photolytic decomposition reaction to occur because it provides the necessary energy to break the bonds within the reactant molecules. Without light, the reaction would not proceed as there wouldn't be enough energy to overcome the activation energy barrier.

Other Types of Reactions:
- Electrolytic decomposition reactions: These reactions involve the decomposition of compounds using electricity as a catalyst. They do not require light.
- Combination reactions: These reactions involve the union of two or more substances to form a single compound. They do not require light.
- Thermolytic decomposition reactions: These reactions involve the decomposition of compounds through the application of heat. They do not require light.

In Summary:
Among the given options, photolytic decomposition reactions specifically require light as a catalyst. Light provides the energy needed to break the bonds within the reactant molecules, allowing the reaction to proceed.
