What does one mean by exothermic and endothermic reaction give example?

A chemical reaction is defined as endothermic when the amount of heat absorbed during the reaction is greater than the amount of heat given off. A reaction that is endothermic is also called a ‘heat of reaction.’ In an exothermic reaction, the amount of heat given off is greater than the amount absorbed. A reaction that is exothermic is also called a ‘heat of reaction.’ This is denoted by a negative heat of reaction.

What is an exothermic and endothermic reactions give example?

An exothermic reaction is one where there is an absorption of heat, as a result of the reaction, and a loss of heat energy to the surrounding environment. An endothermic reaction is one where there is an absorption of heat energy from the surrounding environment, as a result of the reaction.

What does exothermic and endothermic

A reaction is said to be endothermic when the product requires more heat to form than the sum of the heat absorbed or given off during the reaction. A reaction is said to be exothermic when the product absorbs energy. This is usually because the potential energy of the products is lower than the sum of the potential energy of the reactants.

What do exothermic and endothermic reactions mean?

A reaction is endothermic if it absorbs thermal energy. For example, when ice absorbs thermal energy from the surrounding environment, it melts. An endothermic reaction is also known as a heat absorption reaction. By contrast, a reaction that gives off thermal energy is an exothermic reaction. A gas that converts to a solid absorbs thermal energy while freezing. A gas that turns into a liquid absorbs thermal energy while boiling. An exothermic reaction is also known as a heat transfer reaction.

What is exothermic and endothermic reaction give an example?

A reaction which absorbs thermal energy, i.e. absorbs heat, is exothermic. And a reaction that gives off thermal energy when it occurs, i.e. releases heat, is endothermic.
