Smart Which Is Exothermic Reaction

The word exothermic is made up of exo which means outwards and thermos which means heat so exothermic reaction literally means reaction in which the heat goes outwards.

Which is exothermic reaction. The exothermic reaction is the opposite of an endothermic reaction. Updated January 14 2019 An exothermic reaction is a chemical reaction that releases heat and has a negative enthalpy -ΔH and positive entropy ΔS. A reaction that is chemical in nature and is characterized by the release of energy in the form of heat or light is called an exothermic reaction.

In an exothermic reaction change in enthalpy ΔH will be negative. Q1 6 marks An exothermic reaction is sometimes. In other words the activation energy needed to initiate the reaction is less than the energy it releases.

Keep reading to learn more about exothermic reactions and to identify examples of exothermic reactions in real life. Lets explore the exothermic reactions occurring around us. Chances are there are examples of exothermic reactions all around you.

For example the burning of wood releases heat. The energy is usually transferred as heat. Exothermic reactions These are reactions that transfer energy to the surroundings ie the energy exits from the reaction hence the name exothermic.

A chemical reaction is said to be exothermic when it releases energy in the form of heat. An exothermic reaction is a heat source. Exothermic reactions are chemical reactions that produce heat.

In chemistry an exothermic reaction refers to a chemical reaction that results in the release of some quantity of energy normally in the form of light or heat. The system reaction releases heat to the surroundings as the reactants transform into products.
