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.
Please answer the slide #02. Thank you
![2. Predict how the value of K changes as the temperature is increased in this
equation: N2(g) + O2(g) = 2NO(g) AH° = 181 kJ
%3D
Consider the following equilibrium, for which AH < 0
2SO22) + Ozle) = 2 SO3(g)
3. How will each of the following changes affect an equilibrium mixture of the three gases:
a. Oze) is added to the system
b. The volume of the reaction vessel is doubled
c. A catalyst is added to the mixture
d. The total pressure of the system is increased by adding a noble
e. SO3(6) is removed from the system
