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.
![**Classify Each Chemical Reaction**
Below are four chemical reactions. For each reaction, classify the type by selecting all applicable categories.
1. **Reaction:** NaOH (aq) + HBrO (aq) → NaBrO (aq) + H₂O (l)
**Type of Reaction:**
- Combination
- Single replacement
- Double replacement
- Decomposition
- Precipitation
- Combustion
- Acid-base
2. **Reaction:** MgI₂ (aq) + Pb(NO₃)₂ (aq) → Mg(NO₃)₂ (aq) + PbI₂ (s)
**Type of Reaction:**
- Combination
- Single replacement
- Double replacement
- Decomposition
- Precipitation
- Combustion
- Acid-base
3. **Reaction:** CH₃CH₂OH (l) + 3O₂ (g) → 2CO₂ (g) + 3H₂O (g)
**Type of Reaction:**
- Combination
- Single replacement
- Double replacement
- Decomposition
- Precipitation
- Combustion
- Acid-base
4. **Reaction:** MgCO₃ (s) → MgO (s) + CO₂ (g)
**Type of Reaction:**
- Combination
- Single replacement
- Double replacement
- Decomposition
- Precipitation
- Combustion
- Acid-base
**Explanation of Reactions:**
- **NaOH + HBrO Reaction:** This involves the formation of water and salt, characteristic of an acid-base reaction.
- **MgI₂ + Pb(NO₃)₂ Reaction:** Lead(II) iodide precipitates out of solution, indicating a double replacement reaction.
- **CH₃CH₂OH + O₂ Reaction:** Ethanol combustion produces carbon dioxide and water, typical of a combustion reaction.
- **MgCO₃ Reaction:** This is a decomposition reaction where a single compound is broken down into two simpler substances.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb516f95e-88c6-493f-82a8-a9d7f3dd16fa%2F1aefb848-2b01-4a25-b52f-a56b858faf22%2Fjq7spcx_processed.jpeg&w=3840&q=75)
