What is an exothermic reaction?

Answer 1

An exothermic reaction is a chemical reaction that is done by the release of heat. It gives out energy to its surroundings. The energy needed for the reaction to occur is less than the total energy released.

Answer 2

In this process bond breaking always requires energy while bond making always release energy. The balance between these two processes result in two types of reactions exothermic and endothermic reaction. When the energy released by bond forming is greater than the energy consumed by bond breaking there is a net release of chemical energy. This type of reaction is called exothermic reaction+ it is a chemical reaction that releases energy in the form of light or heat.

Answer 3

A chemical reaction accompanied by the evolution of heat.

Answer 4

A chemical reaction which gives off heat. Endothermic reactions take heat in from their surroundings.

Answer 5

A reaction that releases heat when it is performed.

Answer 6

Exothermic reactions produce heat when they react.

Endothermic reactions require heat to react.

Answer 7

Exothermal is a type of chemical or nuclear reaction in which energy is liberated.

Answer 8

An exothermic reaction is a chemical reaction that releases energy by light or heat.
