Endo and Exothermic reactions

What is the definition of an endothermic reaction?

• A chemical reaction that absorbs heat from its surroundings.

• A chemical reaction that occurs at extremely high temperatures.

• A chemical reaction that releases heat into its surroundings.

• A chemical reaction that does not involve heat.

What is the definition of an exothermic reaction?

• A chemical reaction that absorbs energy in the form of heat or light.

• A chemical reaction that occurs at a very slow rate.

• A chemical reaction that does not involve any energy change.

• A chemical reaction that releases energy in the form of heat or light.
