Endothermic reaction is a type of chemical reaction that absorbs energy. Energy is a property of objects.
energy released by the reaction or energy absorbed.
The energy required to start a chemical reaction is called activation energy. It is the minimum amount of energy needed to initiate a reaction by breaking the chemical bonds of the reactants. This energy barrier must be overcome for the reaction to proceed.
A chemical reaction that transfers energy from the reactants to the surroundings is referred to as an exothermic reaction. A reaction that takes energy in is endothermic.
A chemical reaction need an activation energy to start.
Chemical energy is potential energy until the chemical reaction puts atoms and molecules in motion. Heat energy (KE) is often the result of a chemical reaction.
chemical reaction
Endothermic, if the energy is in the form of heat.
For most chemical reactions, energy is required to supply an "activation energy" required before reaction.
A chemical reaction that produces energy is said to be exothermic. In comparison, if it consumes energy it is endothermic.
