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.
![**Part D**
**Structure:**
\[ \text{CH}_3\text{CHCH}_2\text{CH}_3 \]
\[ \quad | \]
\[ \text{OH} \]
**Instruction:**
Draw all missing reactants and/or products in the appropriate boxes by placing atoms on the canvas and connecting them with bonds. Add charges where needed.
**Diagram Description:**
The image displays two main boxes connected by an arrow indicating a reaction or transformation.
- **Left Box (Reactant):**
- Contains a sulfuric acid molecule (\(\text{H}_2\text{SO}_4\)).
- The sulfur atom is centrally located, double-bonded to two oxygen atoms, and single-bonded to two hydroxyl groups (\(\text{OH}\)).
- **Right Box (Product):**
- Displays a molecule of 2-butanol.
- The structure is \(\text{H}_3\text{CCH(OH)CH}_2\text{CH}_3\).
- The alcohol group (\(\text{OH}\)) is marked with red color and a lone pair of electrons.
**Tools:**
A palette with elements like hydrogen (H), carbon (C), nitrogen (N), oxygen (O), sulfur (S), and chlorine (Cl), as well as other elements like bromine (Br), iodine (I), phosphorus (P), and fluorine (F) is present on the right side for drawing.
This setup allows for editing chemical structures by drawing or modifying molecules and adding necessary components.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa579509f-2f23-4d79-a20d-edce94e2128f%2F427c2623-ab13-41ca-91ec-a67b75265ab3%2Fk4nt8um_processed.png&w=3840&q=75)
