Answer

To solve the question regarding Deacon's process of manufacture of chlorine, we will break down the information provided in the video transcript into a structured solution.

### Step-by-Step Solution:

1. **Understanding Deacon's Process**:
Deacon's process is a method for producing chlorine gas (Cl2) through the oxidation of hydrochloric acid (HCl) using atmospheric oxygen (O2) in the presence of a catalyst, typically copper(II) chloride (CuCl2).

2. **Identifying the Reaction**:
The main chemical reaction for Deacon's process can be represented as:
\[ 4 \text{HCl} + \text{O}_2 \xrightarrow{\text{CuCl}_2, 723 \text{ K}} 2 \text{Cl}_2 + 2 \text{H}_2\text{O} \]
This equation shows that four moles of hydrochloric acid react with one mole of oxygen to produce two moles of chlorine gas and two moles of water.

3. **Conditions of the Reaction**:
- The reaction occurs at a temperature of 723 Kelvin.
- Copper(II) chloride (CuCl2) acts as a catalyst, facilitating the reaction without being consumed.

4. **Products of the Reaction**:
The products formed in this reaction are:
- Chlorine gas (Cl2)
- Water (H2O)

5. **Summary of the Process**:
In summary, Deacon's process is an industrial method for producing chlorine gas by oxidizing hydrochloric acid with oxygen, using CuCl2 as a catalyst at elevated temperatures.

### Final Equation:
The final balanced equation for Deacon's process is:
\[ 4 \text{HCl} + \text{O}_2 \xrightarrow{\text{CuCl}_2, 723 \text{ K}} 2 \text{Cl}_2 + 2 \text{H}_2\text{O} \]
