What is the theoretical yield of ammonia (in grams) if 16.55 grams of nitrogen gas and 10.15 grams of hydrogen gas are allowed to react? The enthalpy of this reaction is 92.22 kj.
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.

![Introduction:
While the majority component of air is nitrogen (N₂), the gas is very unreactive because of its stability due to the triple
bonds that hold the nitrogen atoms together. Nitrogen gas is, therefore, relatively unavailable for chemical reactions.
One of the few ways to "fix" nitrogen, making a nitrogen compound from the elemental nitrogen in the atmosphere, is
the Haber process (aka Haber-Bosch process). In this reaction, nitrogen gas combines with hydrogen gas to yield
ammonia. The enthalpy (AH) of this reaction is -92.22 kJ.
This process was discovered by the German chemist Fritz Haber in the early twentieth century. Through extensive
experimentation, Haber found the conditions that would produce adequate yields (at a temperature of about 500 °C and
a pressure of about 200 atm). This process holds a significant importance today because of its application in the
industrial production of ammonia-based fertilizer. In 1918, Haber received the Nobel Prize in Chemistry for his work.
However, a lot of controversy followed the Nobel Prize award.
For this experiment, 16.55 grams of nitrogen gas and 10.15 grams of hydrogen gas are allowed to react in the reaction
vessel. The ammonia vapor that is produced is then condensed, liquefied, and collected into a collection vessel.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F94f8a26f-fadb-4c4a-875a-ee5a075b30f4%2Fbcba209b-9645-4dad-af65-aa59dc7df3ce%2Fete2lr8_processed.jpeg&w=3840&q=75)
