Which Photochemical reactions proceed only under the influence of light are called?
Photochemical reactions that only proceed under the influence of light are called photoreactions. This type of reaction involves the absorption of photons to initiate a chemical reaction. The rate and efficiency of photoreactions are typically dependent on the intensity and wavelength of light.
What do you mean by photochemical reaction?
A photochemical reaction is a chemical reaction that is initiated by light energy. When light of a certain wavelength is absorbed by molecules, it can excite them to a higher energy state, leading to reactions that may not occur under normal conditions. Photosynthesis in plants and certain types of photodegradation of pollutants are examples of photochemical reactions.
Which of the following photosynthetic reactions describe the reactions in which photolysis occurs?
Photolysis occurs in the light-dependent reactions of photosynthesis. These reactions include the light absorption by chlorophyll, splitting of water into oxygen and protons, and the generation of ATP and NADPH.
Is rusting of iron is photochemical process?
No, rusting of iron is not a photochemical process. Rusting is a chemical reaction that occurs in the presence of moisture and oxygen, leading to the formation of iron oxide. Photochemical processes involve light as a driving force for chemical reactions.
Is activation energy for thermal and photochemical reactions same?
No, activation energy for thermal and photochemical reactions is typically different. Thermal reactions involve the breaking and making of chemical bonds due to heat energy, while photochemical reactions are initiated by light energy. The activation energy for photochemical reactions is usually lower than that of thermal reactions.

Is the Ability to react with light - chemical or physical?
The ability to react with light is a physical process known as photochemical reactions. In these reactions, molecules absorb light energy, which excites the molecules and leads to a chemical transformation.
What is the statement of Stark-Einstein's law of photochemical equivalence?
Stark-Einstein's law of photochemical equivalence states that each photon absorbed or emitted in a photochemical reaction is associated with the activation of one molecule. This law helps to explain the relationship between light energy and the number of molecules undergoing photochemical reactions.
What is an example of light and electricity bringing chemical reactions?
Photosynthesis is a photochemical reaction.Sodium chloride electrolysis is an electrochemical reaction.

The activation energy for photochemical reactions is usually lower than that of thermal reactions.
What is the decomposition reaction caused by light called?
The decomposition reaction caused by light is called photolysis. This process involves the breaking down of a compound into simpler substances by absorbing light energy.
Which describes the role of sunlight in chemical reactions?
Sunlight can initiate or accelerate some chemical reactions by providing the energy needed to break chemical bonds. This process is called photochemical reaction. Sunlight can also be essential in photosynthesis, where plants use it to convert carbon dioxide and water into glucose and oxygen.
Can light transfer energy?
Yes, light can transfer energy as it carries electromagnetic radiation. The energy carried by light can interact with matter, causing processes such as heating, photochemical reactions, and the generation of electricity in solar cells.
After light hits photo system 1 it's energy is used to produce what molecule?
After light hits photosystem I, its energy is used to produce NADPH through the process of photochemical reduction. NADPH is an important molecule that plays a key role in carrying and transferring electrons for various metabolic reactions in the cell.
