If energy is absorbed by the reaction that is taking place, where will the heat be absorbed from? What will happen to the temperature of the surrounding water in the calorimeter? Does the amount of water present in a calorimeter affect the change in temperature? How? A neutralization reaction is a highly exothermic reaction. Would you expect the temperature of the water to increase or decrease? Explain in terms of system and surroundings. If you knew the temperature change in the water, its mass and its specific heat, what could you do with this information? How could you use this to find the amount of heat lost during the reaction? (Hint: think about whether the signs on loss and gain of heat are the same)

Thermochemistry

Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.    

Exergonic Reaction

The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
