`4HCl+O_(2)overset(CuCl_(2))rarr2Cl_(2)+2H_(2)O` The above reaction of chlorine preparation is of

Options

A. Deacon's process
B. Contact process
C. Either (a) or (b)
D. None of these

Answer

To solve the question regarding the reaction \(4HCl + O_2 \overset{CuCl_2}{\rightarrow} 2Cl_2 + 2H_2O\) and identify the type of reaction for chlorine preparation, we can follow these steps:

### Step 1: Identify the Reactants and Products
The reactants in the reaction are hydrochloric acid (HCl) and oxygen (O2). The products are chlorine gas (Cl2) and water (H2O).

**Hint:** Look at the chemical equation to determine what substances are being transformed.

### Step 2: Analyze the Role of CuCl2
Copper(II) chloride (CuCl2) acts as a catalyst in this reaction. It facilitates the reaction without being consumed in the process.

**Hint:** Recognize that catalysts speed up reactions and are not part of the final products.

### Step 3: Determine the Type of Reaction
This reaction involves the oxidation of HCl, where chlorine is liberated from hydrochloric acid. The process can be classified as a deacon's process, which is a method of producing chlorine gas.

**Hint:** Consider the historical context of the reaction and its applications in industrial processes.

### Step 4: Conclude the Type of Reaction
Since the reaction is specifically designed to produce chlorine gas from hydrochloric acid in the presence of oxygen and a catalyst, we can conclude that this reaction is known as the Deacon's process.

**Hint:** Recall that specific names are often given to well-known reactions in chemistry, especially those used in industrial applications.

### Final Answer
The above reaction of chlorine preparation is known as the **Deacon's process**.
