Do Exothermic reactions not require any activation energy.?
Exothermic reactions do require activation energy to initiate the reaction, even though they release heat once they proceed. Activation energy is the minimum energy needed for reactants to overcome the energy barrier and transform into products. Once this barrier is crossed, the reaction can continue and release energy in the form of heat. Thus, while exothermic reactions release energy overall, they still need some energy input to get started.
Which type of reaction requires more activation energy?
Endothermic reactions typically require more activation energy compared to exothermic reactions. This is because in an endothermic reaction, energy is absorbed from the surroundings to break bonds and form new ones, which requires more energy input to overcome the activation barrier.
What type of reaction releases energy and does not require initial energy to occur?
All reactions require an activation energy. Some appear not to because that energy is provided enough by their temperature. Thus, there is no reaction that does not require any initial energy to occur. A reaction that results in an overall release of energy is called an exothermic reaction.
The amount of activation energy related to whether a reaction is exothermic or endothermic?
The amount of activation energy required for a reaction is independent of whether the reaction is exothermic or endothermic. Activation energy is the energy needed to reach the transition state, allowing reactants to be converted into products. Exothermic reactions release energy as products form, while endothermic reactions absorb energy. Therefore, both types of reactions can have varying amounts of activation energy, depending on other factors such as the specific reactants and the reaction pathway.
A process or reaction which releases heat to the surroundings is said to be?
Reactions that require energy in the form of heat are called endothermic.

Does endothermic have a high or low activation energy?
An endothermic reaction would not necessarily have either a high or low activation energy; it could be either and would depend on the reactants. Also, the activation energy alone does not determine if a reaction is endothermic or exothermic; a low or high activation energy could be part of an endothermic or exothermic reaction, again depending on the reactants.

Do reactions require activation energy?
yes
Why does exothermic reactions need activation energy?
Even though exothermic reactions release energy overall, they still require an initial input of energy to overcome the activation energy barrier. This energy is needed to initiate the reaction by breaking the existing bonds in the reactant molecules. Once this barrier is crossed, the reaction proceeds spontaneously and releases energy in the form of heat.
Which reactions requires or stores energy?
Endothermic reactions require energy while exothermic reactions release energy.
Why does an exothermic reaction need activeation energy?
Exothermic reactions need activation energy to start, but they also need it to keep going to build up heat. At the end of the reaction, the products have less energy than the reactants. This produces heat. In order for this to happen, the exothermic reaction needs activation energy.
A process or reaction which releases heat to the surroundings is said to be?
Reactions that require energy in the form of heat are called endothermic.
Is it true or false that all chemical reactions require an initial input of energy called catalysis?
False. Not all chemical reactions require catalysis. Some reactions occur spontaneously, while others may require an initial input of energy in the form of activation energy. Catalysis is a process that lowers the activation energy required for a reaction to occur, but it is not necessary for all reactions.
How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
