Chemical reactions occur spontaneously when the free energy of the product is less than the free energy of the reactants. Free energy is a combination of thermal energy (heat) and entropy. If thermal energy is absorbed during a reaction, there must be an exceptionally large increase in entropy to give a net reduction in free energy.

How do chemical reactions that absorbs energy are called?
Endothermic reaction = absorbs energyExothermic reaction = releases energy
Reactions that release heat as bonds are broken are called .?
exothermic
Differentiate exothermic from endothermic reactions?
Exothermic reactions give out heat; Endothermic ones absorb heat.
How does an exothermic reaction differ from n endothermic reaction?
Exothermic reactions release heat. Endothermic reactions take in heat.
What is the term for the reactions that required energy input?
endothermic reactions
What are some examples of endothermic reactions that are endothermic as well?
All ENDOthermic reactions are of course ENDOthermic by themselves, aren't they?
A chemical reaction that requires a net input of energy?
"Activation Energy reactions"; Endothermic reactions require energy.
How do chemical reactions that absorbs energy are called?
Endothermic reaction = absorbs energyExothermic reaction = releases energy
Which reactions requires or stores energy?
Endothermic reactions require energy while exothermic reactions release energy.
Reactions that release heat as bonds are broken are called .?
exothermic
Are exothermic reactions chemical?
Most chemical reactions are exothermic, that is, they release a certain amount of heat as a by-product of the reaction. Endothermic reactions, those which absorb heat, also do occur, but they are more rare. Endothermic reactions are driven by entropy only, whereas exothermic reactions are driven by the energy that is released. The more energy is released, the more easily the reaction will occur.
Differentiate exothermic from endothermic reactions?
Exothermic reactions give out heat; Endothermic ones absorb heat.
Is combustion exothermic or endothermic?
exothermic reactions are the reactions which give out heat and endothermic reactions are the reaction which absorb heat.so combustion is an exothermic reaction.
What are reactions that take in heat energy?
endothermic reactions
Are nematodes ectothermic or endothermic?
There are other chemical reactions that must absorb energy in order to proceed. These are endothermic reactions. So I think they are Endothermic...
Are Ombustion reactions exothermic or endothermic?
Combustion reactions are exothermic.
What is the term for the reactions that required energy input?
endothermic reactions
