What is the name for the following chemical reaction?
`CO(g) + H_2O(g)to CO_2(g) + H_2(g)`

Answer

To determine the name of the chemical reaction represented by the equation:

\[ CO(g) + H_2O(g) \rightarrow CO_2(g) + H_2(g) \]

we can follow these steps:

### Step 1: Identify the Reactants and Products
- The reactants in the reaction are carbon monoxide (CO) and water (H₂O).
- The products formed are carbon dioxide (CO₂) and hydrogen gas (H₂).

### Step 2: Analyze the Reaction Type
- This reaction involves the conversion of carbon monoxide and water into carbon dioxide and hydrogen gas.
- It is a redox reaction where carbon monoxide is oxidized to carbon dioxide, and water is reduced to hydrogen gas.

### Step 3: Recognize the Specific Reaction
- This particular reaction is known as the "Water Gas Shift Reaction."
- It typically occurs in the presence of a catalyst and is used to increase the yield of hydrogen gas from syngas (a mixture of carbon monoxide and hydrogen).

### Step 4: Conclude the Name of the Reaction
- Therefore, the name of the reaction is the **Water Gas Shift Reaction**.
