An endothermic reaction absorbs heat. It cannot proceed without the addition of heat.
An exothermic reaction releases heat. Since heat causes chemical reactions to go faster, an exothermic reaction can "feed on itself" and get out of control, releasing damaging amounts of heat and, if proceeding in a closed container, causing an explosion.
energy released by the reaction or energy absorbed.
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
An endothermic change requires heat, and an exothermic change releases heat.
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
The difference between endothermic and exothermic energy is that exothermic energy is the reaction that releases energy and endothermic is the reaction in ehich energy is absorbed.
You can generally tell by changes in temperature, whether you have an exothermic reaction which produces heat, or an endothermic reaction which consumes heat.
energy released by the reaction or energy absorbed.
EXTREMELY!!!!! exothermic. As in fires and explosions exothermic.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
An endothermic change requires heat, and an exothermic change releases heat.
An endothermic reaction absorbs energy, making its environment cooler. Ab exothermic reaction releases energy, making its environment warmer.
The terms "endothermic" and "exothermic" refer to whether a chemical reaction absorbs or releases heat, respectively. In an endothermic reaction, heat is absorbed from the surroundings, while in an exothermic reaction, heat is released into the surroundings.
Endothermic reactions and exothermic reactions all involve something called an enthalpy change: a change in the amount of energy a chemical contains. The difference here is that exothermic reactions release heat energy to their surroundings, whereas endothermic reactions absorb heat from their surroundings (in effect, getting colder).
An endothermic reaction is when the atoms break and need to abosrb heat. An exothermic reaction is whe new bonds are made and give heat to the surroundings.
Any reaction categories into exothermic and endothermic based upon change in enthalpy of reaction. If difference in enthalpy of product and reactant comes positive value then it is termed as endothermic and if it is negative value then exothermic reaction. Usually, vaporisation is considered as exothermic due to release in energy.
