If heat flows from the system to the surroundings, the reaction gave off energy. Therefore the change in enthalpy for the reaction is negative and this is called an exothermic reaction. As an example of a reaction, let's look at the decomposition of hydrogen peroxide to form liquid water and oxygen gas.
