Deacon's process is used for the manufacture of

Options

A. `HNO_(3)`
B. `I_(2)`
C. `Cl_(2)`
D. `Br_(2)`

Answer

**Step-by-Step Text Solution:**

1. **Understanding Deacon's Process**: Deacon's process is a chemical method used for the production of chlorine gas (Cl2) from hydrochloric acid (HCl). It involves the oxidation of HCl in the presence of a catalyst.

2. **Chemical Reaction**: The reaction can be summarized as follows:
\[ 4 \text{HCl(g)} + \text{O}_2(g) \rightarrow 2 \text{Cl}_2(g) + 2 \text{H}_2\text{O}(g) \]
This equation indicates 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. **Catalyst Used**: The process typically employs transition metal oxides as catalysts, with copper(II) chloride (CuCl2) being a common choice. The presence of the catalyst allows the reaction to occur at a moderate temperature, around 723 K (approximately 450 °C).

4. **Exothermic Nature**: The Deacon process is exothermic, meaning it releases heat during the reaction. This characteristic is important for the efficiency of the process.

5. **Conclusion**: Based on the information provided, Deacon's process is specifically used for the manufacture of chlorine gas (Cl2).

**Final Answer**: Deacon's process is used for the manufacture of chlorine gas (Cl2).
