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.
![**Title: Preparation of Potassium Perchlorate**
**Introduction:**
Potassium perchlorate (KClO₄) is a chemical compound commonly used in various applications, including pyrotechnics and as an oxidizing agent in laboratory settings. It can be prepared through a sequence of chemical reactions involving chlorine gas (Cl₂), potassium hydroxide (KOH), and potassium chloride (KClO₃).
**Chemical Reactions:**
1. **First Reaction:**
\[ \text{Cl}_2(g) + 2 \text{KOH}(aq) \rightarrow \text{KCl}(aq) + \text{KClO}(aq) + \text{H}_2\text{O}(\ell) \]
2. **Second Reaction:**
\[ 3 \text{KClO}(aq) \rightarrow 2 \text{KCl}(aq) + \text{KClO}_3(aq) \]
3. **Third Reaction:**
\[ 4 \text{KClO}_3(aq) \rightarrow 3 \text{KClO}_4(aq) + \text{KCl}(aq) \]
**Problem Statement:**
Determine the mass of chlorine gas (Cl₂) required to produce 165 kg of potassium perchlorate (KClO₄).
