How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require 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.
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.
How does an atom react at low temperatures?
Chemical reactions require what is known as an "activation energy" to get started; if the reaction is exothermic, it may produce enough energy that it becomes self-sustaining. At lower temperatures there is less energy available, and so atoms are less likely to engage in chemical 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.
How can an endothermic reaction be spontaneous at room temperature?
Exothermic, as endothermic reactions require activation energy.
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
Why does exothermic reactions need activation energy?
so the reaction can get started
Do reactions require activation energy?
yes
Which reactions requires or stores energy?
Endothermic reactions require energy while exothermic reactions release 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.
All reactions require activation energy?
No. Some reactions such as one material dissolving into another do not require a starting 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.

Is it true or false that all chemical reactions require an initial input of energy called catalysis?
FalseAll chemical reactions require an initial input of energy called activation energy.
