Acid rain results from the reaction of nitrogen dioxide, a major component of photochemical smog which is the brown gas hanging over major cities, in the air mixing with water vapor to form nitric acid in the reaction shown below. 3NO2(g) + H2O(g) ----> 2HNO3(aq) + NO(g) Assuming this reaction is happening in the open air, when 69L of Nitrogen dioxide are reacted with water, how many liters of nitrogen monoxide will be produced in the atmosphere?
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.
