An endothermic reaction is a chemical reaction that absorbs heat energy from the surroundings, causing the temperature to decrease, and is often represented by a negative H (enthalpy) value.
An exothermic reaction is a chemical reaction that releases heat energy to the surroundings, causing the temperature to increase, and is often represented by a positive H (enthalpy) value.
