Light reaction takes place. The first step of photosynthesis
The minimum amount of energy needed for a reaction to take place is called the activation energy. This energy barrier must be overcome for reactants to transform into products, allowing the reaction to proceed. Activation energy can be influenced by factors such as temperature and the presence of catalysts, which can lower the energy required for the reaction to occur.
no
To determine which reaction will most likely take place, it's essential to consider the reactants involved, their properties, and the reaction conditions. Typically, reactions that are thermodynamically favorable, such as those that lead to increased stability or lower energy states, are more likely to occur. Additionally, factors like concentration, temperature, and the presence of catalysts can influence the likelihood of a reaction taking place. Without specific details about the reactants or conditions, it's challenging to predict the exact reaction.
Light reaction is taking place on thylakoids.Dark reaction take place in stroma.
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.
For a reaction between oxygen molecule and hydrogen molecule to take place the bond between the two oxygen atom in O2 and the two hydrogen atom in H2 is required to be breaked. For this process a high temperature is needed which is not possible at room temperature. Since no bond breaks to make an reacting atom, the reaction does not takes place at room temperature
Endothermic reactions need heat. Exothermic reactions give off heat.
Yes. The reaction would be Ca + H2O --> Ca(OH)2 + H2. Hope that helped.
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
The molecules will have less energy because temperature, especially heat, proviedes energy and the chemical reaction will take place in a lesser amount of time than with a chemical reaction under high temperature.
