Which of the following products is produced during the given chemical reaction?
`CO(g) + H_(2) (g) underset(ZnO, Cr_(2) O_(3))overset(575 K)to ?`

Options

A. Ethanol
B. Methanal
C. Methanol
D. Ethanal

Explanation

To determine the product of the given chemical reaction \( CO(g) + H_2(g) \) under the conditions of \( ZnO, Cr_2O_3 \) at \( 575 \, K \), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants in the reaction are carbon monoxide (CO) and hydrogen gas (H2).

2. **Recognize the Reaction Type**: The reaction involves the reduction of carbon monoxide in the presence of hydrogen. This is a typical reaction in the synthesis of alcohols from carbon monoxide and hydrogen.

3. **Conditions of the Reaction**: The reaction is carried out at a temperature of 575 K and in the presence of catalysts \( ZnO \) and \( Cr_2O_3 \). These catalysts are known to facilitate the conversion of CO and H2 into alcohols.

4. **Determine the Product**: Under these conditions, the main product formed from the reaction of CO and H2 is methanol (\( CH_3OH \)). This is a well-known reaction in the methanol synthesis process.

5. **Select the Correct Option**: Among the options provided, we need to identify which one corresponds to methanol. The options given are:
- A) Ethanol
- B) Methanol
- C) Methanol (repeated)
- D) Ethanol (repeated)

Since methanol is \( CH_3OH \), we can see that option B or C (both are methanol) is the correct answer.

### Final Answer:
The product produced during the reaction \( CO(g) + H_2(g) \) under the given conditions is **Methanol** (\( CH_3OH \)). Therefore, the correct option is **B or C**.
