"Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this reaction is one of the ways hydrogen is made industrially. A chemical engineer studying this reaction fills a 100 L tank with 13. mol of carbon monoxide gas and 23. mol of water vapor. When the mixture has come to equilibrium he determines that it contains 4.0 mol of carbon monoxide gas, 14. mol of water vapor and 9.0 mol of carbon dioxide. The engineer then adds another 8.0 mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of hydrogen after equilibrium is reached the second time. Round your answer to 2 significant digits. mol X

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.

Transcribed Image Text:"Synthesis gas" is a mixture of carbon monoxide and water vapor. At high temperature synthesis gas will form carbon dioxide and hydrogen, and in fact this
reaction is one of the ways hydrogen is made industrially.
A chemical engineer studying this reaction fills a 100 L tank with 13. mol of carbon monoxide gas and 23. mol of water vapor. When the mixture has come to
equilibrium he determines that it contains 4.0 mol of carbon monoxide gas, 14. mol of water vapor and 9.0 mol of carbon dioxide.
The engineer then adds another 8.0 mol of water, and allows the mixture to come to equilibrium again. Calculate the moles of hydrogen after equilibrium is
reached the second time. Round your answer to 2 significant digits.
