Nitric acid neutralizes potassium hydroxide. To determine the heat of reaction, a student placed 46.6 mL of 3.0 M HNO3 in a coffee cup calorimeter, noted that the temperature was 26.3°C, and added 46.6 mL of 3.0 M KOH, also at 26.3°C. The mixture was stirred quickly with a thermometer, and its temperature rose to 38.8°C. Enter the balanced equation for the reaction. Do not include physical states.

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.
