Endothermic Reaction and Exothermic Reaction  Question : What is the difference between endothermic reaction and exothermic reaction?

Endothermic and Exothermic reactions are used in our everyday life.

Endothermic reaction is when a reaction that absorbs energy in the form of heat. Photosynthesis is an example endothermic reaction because plants use the energy from the sun to convert carbon dioxide and water into glucose and oxygen. Another example is when ice is frozen and then it melts.

sunlight Photosynthesis= H 2 0 + C0 2  > O 2 + C 6 H 12 O 6 



Exothermic reaction is when a reaction releases energy in the form of heat. An example of this is when a candle is lit, and it releases heat.
