Question

A chemical reaction takes place in which energy is released a range of the reaction characteristics in order from start to finish

Answer 1

Ummm may i ask how is this related with the subject English, it should be  either chemistry or science?

Answer 2

Endothermic reactions, on the other hand, absorb heat and/or light from their surroundings. For example, decomposition reactions are usually endothermic. In endothermic reactions, the products have more enthalpy than the reactants. Thus, an endothermic reaction is said to have a positive enthalpy of reaction. This means that the energy required to break the bonds in the reactants is more than the energy released when new bonds form in the products; in other words, the reaction requires energy to proceed
