`CO(g)+H_(2)overset(575K)underset(ZnO,Cr_(2)O_(3))rarr` ……?

Options

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

Explanation

To solve the question regarding the reaction of carbon monoxide (CO) and hydrogen (H2) in the presence of zinc oxide (ZnO) and chromium trioxide (Cr2O3) at a temperature of 575K, 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. **Understand the Reaction Conditions**: The reaction occurs at a temperature of 575K and involves the catalysts zinc oxide (ZnO) and chromium trioxide (Cr2O3).

3. **Recognize the Type of Reaction**: This reaction is known as the catalytic reduction of carbon monoxide using hydrogen, which is a method for synthesizing methanol.

4. **Write the Balanced Equation**: The balanced chemical equation for the reaction is:
\[ CO(g) + 2H_2(g) \rightarrow CH_3OH(g) \]
This indicates that one molecule of carbon monoxide reacts with two molecules of hydrogen to produce one molecule of methanol (CH3OH).

5. **Identify the Product**: From the balanced equation, we can see that the product formed from this reaction is methanol (CH3OH).

6. **Conclusion**: Therefore, the substance produced during the reaction of CO and H2 in the presence of ZnO and Cr2O3 at 575K is methanol.

### Final Answer:
The product formed is **methanol (CH3OH)**.
