Chemical reaction - Energy, Reactants, Products: Energy plays a key role in chemical processes. According to the modern view of chemical reactions, bonds between atoms in the reactants must be broken, and the atoms or pieces of molecules are reassembled into products by forming new bonds. Energy is absorbed to break bonds, and energy is evolved as bonds are made. In some reactions the energy required to break bonds is larger than the energy evolved on making new bonds, and the net result is the absorption of energy. Such a reaction is said to be endothermic if the energy is in the form of heat. The

FAQs
Photosynthesis Is An Example Of An Exothermic Reaction. An Endothermic Reaction. A Reaction That Gives Off Heat. A Reaction That Emits Energy.? ›
Assertion(A): Photosynthesis is an endothermic reaction. Reason(R): Energy gets released in the process of photosynthesis.
Is photosynthesis A endothermic or exothermic reaction? ›Photosynthesis is an endothermic reaction. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.
Is photosynthesis endothermic or endothermic? ›Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
Is photosynthesis an exothermic or energy releasing process? ›Photosynthesis is endothermic, and the necessary energy is supplied by the absorption of solar radiant energy.
Is photosynthesis an example of a reaction that gives off heat? ›Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.
Is photosynthesis an endothermic reaction True or false? ›Photosynthesis is considered an endothermic reaction because the energy in the form of sunlight is absorbed by the green plants.
Is photosynthesis always endothermic? ›Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun's electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant.
Does photosynthesis release energy? ›In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
What is the reaction of photosynthesis? ›6CO2 + 6H2O + Light C6H12O6 + 6O2
Algae, plants and photosynthetic bacteria take in light through the sun, water molecules from their environment and carbon dioxide from the air and combine these reactants to produce the food i.e. glucose.
Endothermic reactions are the reactions in which energy is required from outside Environment. Photosynthesis is considered an endothermic reaction because plants gets the energy to convert carbon dioxide and water into glucose and oxygen from the outside (Sun) environment.
Is photosynthesis Endergonic or Exergonic? ›
Photosynthesis is an endergonic reaction, as it requires input of energy to synthesize carbohydrate.
Why is photosynthesis endothermic? ›Photosynthesis is an endothermic reaction as it requires light energy to react carbon dioxide and water to produce glucose and oxygen. The light energy required is absorbed by a green pigment called chlorophyll in the leaves.
What is photosynthesis an example of? ›Photosynthesis is an example of a metabolic process with 2 stages. Both the stages need light (direct or indirect sunlight).
What reaction gives off heat? ›Exothermic reactions are chemical reactions that produce heat.
Is photosynthesis caused by heating? ›Plants produce food or energy in the form of sugar using water, carbon dioxide, and sunlight in the presence of chlorophyll and emit oxygen as a byproduct. Temperature has an impact on the rate of photosynthesis. The rate of photosynthesis increases as the temperature rises.
Why is photosynthesis is an endothermic reaction? ›The bacteria that do produce oxygen as a by-product of photosynthesis are called oxygenic photosynthetic bacteria. Photosynthesis is an endothermic reaction because sunlight energy is absorbed by green plants during this process.
Why is photosynthesis exothermic reaction? ›An example of an exothermic reaction is cellular respiration. High-energy glucose releases energy as it's broken down. And that energy is used to generate ATP molecules. Since we know that photosynthesis absorbs light energy and stores it in its product glucose, we know that it's an endothermic chemical reaction.
How do you determine if a reaction is endothermic or exothermic? ›So, if a reaction releases more energy than it absorbs, the reaction is exothermic and enthalpy will be negative. Think of this as an amount of heat leaving (or being subtracted from) the reaction. If a reaction absorbs or uses more energy than it releases, the reaction is endothermic, and enthalpy will be positive.
Is the respiration endothermic or exothermic? ›Every living cell breaks down its food to release energy. Reactions that involve liberation of energy and increase in temperature are called exothermic reactions. Thus, respiration is exothermic in nature.
