For SO2 melting and boiling points are 198 K and 263 K respectively. C? values for solid phase are 1.255 J/mol-K at 15 K and 84.185 J/mol-K for greater than 15 K. C? values for liquid phase is 24.937 J/mol-K. For gas phase C? = 49.769 + 4.56*10-3 T J/mol-k where T is in K. Enthalpy of freezing and condensation processes are -7.402 kJ/mol and -24.937 kJ/mol respectively. Determine specific entropy of SO2 at 400 K.
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.
