Two Parter, thank you in advance! The most important commercial process for generating hydrogen gas is the water-gas shift reaction: CH4(g) + H2O(g) --> CO(g) + 3 H2(g) Use the tabulated thermodynamic data to find ΔGo, in kJ. (enter your answer to 4 significant figures) Now calculate ΔGo1150 for this process when it occurs at 1150 K, in kJ. (enter your answer to 4 significant figures) (Use the relationship DeltaG = DeltaH - T*DeltaS) ((The answer is not 39.98 or 214.51 for either of them)
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.
