D. Heterogeneous catalyst

Answer

To solve the question regarding the role of dilute H₂SO₄ in the reaction of sucrose hydrolysis, let's break it down step by step:

### Step 1: Understand the Reaction
The reaction given is:
\[ C_{12}H_{22}O_{11} + H_2O \xrightarrow{dil. H_2SO_4} C_6H_{12}O_6 + C_6H_{12}O_6 \]
This reaction represents the hydrolysis of sucrose (C₁₂H₂₂O₁₁) into glucose (C₆H₁₂O₆) and fructose (C₆H₁₂O₆) in the presence of water and dilute sulfuric acid.

### Step 2: Identify the Role of Dilute H₂SO₄
In this reaction, dilute H₂SO₄ acts as a catalyst. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

### Step 3: Determine the Type of Catalyst
To classify the type of catalyst:
- **Homogeneous Catalyst**: A catalyst that is in the same phase (state) as the reactants.
- **Heterogeneous Catalyst**: A catalyst that is in a different phase than the reactants.

In this reaction, both the reactants (sucrose and water) and the catalyst (dilute H₂SO₄) are in the same phase (aqueous solution). Therefore, we can conclude that dilute H₂SO₄ is a homogeneous catalyst.

### Step 4: Conclusion
Based on the above analysis, the correct answer to the question is that dilute H₂SO₄ is called a **homogeneous catalyst**.

### Final Answer
**Dilute H₂SO₄ is called a homogeneous catalyst.**
