Concept explainers

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.

**Table B: Physical Constants for Water**

| Property | Value |
|----------|-------|
| Heat of Fusion | 334 J/g |
| Heat of Vaporization | 2260 J/g |
| Specific Heat Capacity of H₂O(ℓ) | 4.18 J/g·K |

**Explanation:**

- **Heat of Fusion:** This is the amount of energy required to change 1 gram of solid water (ice) to liquid water at its melting point, without changing its temperature (334 Joules per gram).

- **Heat of Vaporization:** This is the energy needed to convert 1 gram of liquid water to vapor (gas) at its boiling point, without a temperature change (2260 Joules per gram).

- **Specific Heat Capacity of H₂O(ℓ):** It refers to the amount of heat required to raise the temperature of 1 gram of liquid water by 1 Kelvin (or 1 degree Celsius), which is 4.18 Joules per gram per Kelvin.
