Quantum yield of a photochemical reaction refers to the efficiency with which a light-induced process, such as the generation of a particular product or the initiation of a reaction, occurs. It is defined as the number of moles of a product formed per mole of photons absorbed by the system. A high quantum yield indicates that a higher proportion of the absorbed photons lead to the desired outcome.

What is a photosynthetic reaction in a plant cell transforming energy from sunlight into chemical energy?
Photosynthesis. In the process of photosynthesis, light energy is used to convert carbon dioxide and water into glucose (sugar) and oxygen. The energy in the light is converted into the chemical energy in the glucose molecules.
Why does white siver chloride turn grey in sunlight?
White silver chloride turns grey in sunlight due to a chemical reaction known as photo-reduction. When exposed to sunlight, silver chloride decomposes into silver metal and chlorine gas. This leads to the formation of gray-colored silver metal on the surface of the silver chloride.
What is the photo- part of the photosyntheses process?
The photo- part of photosynthesis refers to the light-dependent reactions that occur in the chloroplasts of plant cells. During this phase, light energy is absorbed by chlorophyll and converted into chemical energy in the form of ATP and NADPH, which are used to drive the subsequent light-independent reactions.
How is light energy converted to chemical energy?
Light energy is converted to chemical energy through the process of photosynthesis in plants. During photosynthesis, light energy is used to convert carbon dioxide and water into glucose and oxygen. The glucose produced serves as a chemical energy source for the plant's growth and metabolism.
Is The reverse reaction of photo synthesis is called what?
The reverse reaction of photosynthesis is called cellular respiration. In this process, cells break down glucose and other organic molecules to produce energy in the form of ATP, releasing carbon dioxide and water as byproducts.
What is photo chemical reaction?
chemical reaction brought on by light ( latin: photo - light)
What evidence of a chemical reaction is shown in the photo?
lol what photo
What is the photo-chemical reaction that takes place in the presence of sunlight and is responsible for providing food for everyone?
The photo-chemical reaction that takes place in the presence of sunlight and is the source of food for everyone is called photosynthesis.
How do we see green light?
The process of seeing green light is a photo-chemical reaction in the rods and cones of your retina.
Is lighting of photo flash bulb exothermic or endothermic?
The lighting of a photo flash bulb is exothermic because it releases energy in the form of light and heat when it ignites. This process involves a chemical reaction that produces a sudden burst of light.
What is law of quantum energy and quantum mass?
In the universe energy, matter and go as per quantum. Energy is released in quantum of photon. Electron has a quantum mass. Proton has quantum mass. Both has a quantum charge. Neutron has a quantum mass. Speed of light is a quantum. Big bang is a quantum event essentially occurring at particular mass. It takes a quantum energy for shifting of electrons from one shell to other. In photo-luminescence light energy is released in quantum.
What is another name for light dependent reations of photosynthesis?
The exergonic reaction is a chemical reaction that releases energy (photosynthesis). The product of light dependant reactions is called endergonic reaction. It is a chemical reaction that requires energy.
What is the definition of photo-chemical?
Related to or caused by the chemical action of light
What has the author H Stanley Allen written?
H. Stanley Allen has written: 'Photo-electricity' -- subject(s): Photoelectricity, Electrons 'The quantum and its interpretation' -- subject(s): Quantum theory, Atoms
Define photography from the original Greek?
photography photo-graphy (φωτογραφία) photo (φώς) :light graphy (γράφημα) : drawing a drawing made from light
What is relation of co2 to the photo chemical reaction?
photochemical reaction, a chemical reaction initiated by the absorption of energy in the form of light. The consequence of molecules' absorbing light is the creation of transient excited states whose chemical and physical properties differ greatly from the original molecules. These new chemical species can fall apart, change to new structures, combine with each other or other molecules, or transfer electrons, hydrogen atoms, protons, or their electronic excitation energy to other molecules. Excited states are stronger acids and stronger reductants than the original ground states.
How can photochemical smog be controlled?
if we control the primary precursors of photo chemical smog,such as NO2 and hydrocarbons,the secondary precursors such as ozone and PAN,the photo chemical smog will automatically be reduced.
