no
Light reaction is taking place on thylakoids.Dark reaction take place in stroma.
This is an endothermic reaction.
When food is boiled in water, the process of Maillard reaction does not occur. Maillard reaction is a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor and color. Since the water prevents the surface of the food from reaching a high enough temperature for this reaction to take place, the food does not go brown.
High temperature and high pressure are necessary for fusion reactions to take place in a star. The high temperature is needed to overcome the electrostatic repulsion between positively charged atomic nuclei, while the high pressure is needed to confine the high temperature plasma.
The two necessary conditions for cracking to take place are high temperature and presence of a catalyst. High temperature allows for the breaking of chemical bonds in the hydrocarbon molecules, while the catalyst accelerates the cracking reaction by providing an alternative pathway with lower activation energy.
No reaction occurs between methane (CH4) and chlorine (Cl2) at room temperature because the activation energy required for the reaction to take place is too high. In this case, the C-H bonds in methane are very strong and stable, making it difficult for chlorine to break those bonds and form new compounds. Additionally, the lack of sufficient energy at room temperature prevents the reaction from occurring.
Endothermic. In an endothermic reaction, heat is absorbed from the surroundings in order for the reaction to proceed. This results in a decrease in temperature in the surrounding environment.
No, a reaction will not take place between calcium (Ca) and water (H2O). Calcium is a fairly unreactive metal and does not react with water at room temperature.
In A Chemical Reaction the following take place a) there is evolution of a gas b) change in colour c) change in state d) change in temperature
Lowering the temperature typically decreases the speed of most chemical reactions. This is because lower temperatures decrease the kinetic energy of the molecules involved, resulting in fewer collisions and slower reaction rates.

Light reaction take place in day time. Dark reaction take place at night
