In water gas shift reaction reactant is

Options

A. `H_(2) + H_(2)O`
B. `H_(2) + CO_(2)`
C. `H_(2) + CO + H_(2)O`(g)
D. `H_(2) + D_(2)`

Answer

To solve the question regarding the reactants in the water gas shift reaction, we will follow these steps:

### Step-by-Step Solution:

1. **Understand the Water Gas Shift Reaction**: The water gas shift reaction is a chemical reaction that involves the conversion of carbon monoxide and water into carbon dioxide and hydrogen. It is a crucial step in the Bosch process, which is a method for producing hydrogen gas.

2. **Identify the Reactants**: In the water gas shift reaction, the primary reactants are:
- Carbon monoxide (CO)
- Water (H₂O)

3. **Write the Reaction Equation**: The balanced equation for the water gas shift reaction can be represented as:
\[ \text{CO} + \text{H}_2\text{O} \rightarrow \text{CO}_2 + \text{H}_2 \]
This shows that carbon monoxide reacts with water to produce carbon dioxide and hydrogen.

4. **Evaluate the Options**: Now, let's look at the provided options:
- **Option A**: Hydrogen + Water (Incorrect)
- **Option B**: Hydrogen + Carbon Dioxide (Incorrect)
- **Option C**: Hydrogen + Carbon Monoxide + Water (Correct)
- **Option D**: Hydrogen + Deuterium (Incorrect)

5. **Select the Correct Option**: Based on our understanding and the balanced equation, the correct reactants for the water gas shift reaction are indeed carbon monoxide and water. Therefore, the correct answer is:
- **Option C**: Hydrogen + Carbon Monoxide + Water

### Final Answer:
The reactants in the water gas shift reaction are **Hydrogen + Carbon Monoxide + Water**.
