Describe the role of energy in chemical reactions?
Chemical reactions that release energy often occur spontaneously. Chemical reactions that absorb energy will not occur without energy.
Can chemical reactions absorb energy?
yes they do,the reactions which absorb energy are called endothermic reaction.
How is endothermic reactions differ from exothermic reactions?
Endothermic chemical reactions absorb more energy than they release, while exothermic chemical reactions release more energy than they absorb.
What do chemical reactions that absorb energy need to occur?
They need a source of energy.A Source of Energy
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.

Are chemical reactions that absorb energy will occur without a source of energy?
false
Does a chemical reactions that absorb energy will not occur without a source of energy?
Yes, it is true.
Can chemical reactions absorb energy?
yes they do,the reactions which absorb energy are called endothermic reaction.
How is endothermic reactions differ from exothermic reactions?
Endothermic chemical reactions absorb more energy than they release, while exothermic chemical reactions release more energy than they absorb.
What do chemical reactions that absorb energy needed to occur what is it?
Endothermic reactions absorb heat from the environment.
What are chemical rections that absorb energy?
Endothermic Reactions
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
What do chemical reactions that absorb energy need to occur?
They need a source of energy.A Source of Energy
When is a reaction said to be endothermic?
The chemical reactions that must absorb energy in order to proceed. These are endothermic reactions.
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
