Give one method for industrial preparation CO

Explanation

**Step-by-Step Solution:**

1. **Identify the Compound**: The question asks for a method of industrial preparation of carbon monoxide (CO).

2. **Select a Preparation Method**: One common method for the industrial preparation of carbon monoxide is through the dehydration of formic acid.

3. **Write the Chemical Reaction**: The reaction involves formic acid (HCOOH) being dehydrated in the presence of concentrated sulfuric acid (H₂SO₄) at a temperature of 373 K. The reaction can be represented as follows:
\[ \text{HCOOH} \xrightarrow{\text{H}_2\text{SO}_4, 373 \text{K}} \text{CO} + \text{H}_2\text{O} \]

4. **Explain the Reaction**: In this reaction, formic acid is converted into carbon monoxide and water. The concentrated sulfuric acid acts as a dehydrating agent, facilitating the removal of water from formic acid.

5. **Conclusion**: Therefore, the industrial preparation of carbon monoxide can be achieved through the dehydration of formic acid using concentrated sulfuric acid at elevated temperatures.
