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.
![**Question 24:**
Phthalates, used to make plastics flexible, are among the most abundant industrial contaminants in the environment. Several have been shown to act as hormone mimics in humans by activating the receptors for estrogen, a female sex hormone. In characterizing the compounds completely, the value of ΔH_comb for dimethyl phthalate (C₁₀H₁₀O₄) was determined to be −4685 kJ/mol. If 1.00 g of dimethyl phthalate is combusted in a calorimeter whose heat capacity (C_calorimeter) is 7.854 kJ/°C and at an initial temperature of 20.215 °C, what would be the expected final temperature of the calorimeter?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fbeb4d536-f388-44bc-91f3-a72ed115bd90%2F3fa46d86-9715-4b03-abee-f74629764cd4%2Fawrbe8d_processed.png&w=3840&q=75)
