In the following chemical reaction "zinc oxide reacts with carbon to produce zinc metal and carbon monoxide.
`ZnO+C rarrZn + CO`
The substance getting reduced is _______

Options

A. C is getting reduced to CO
B. ZnO is getting reduced to Zn
C. No substance is getting redused
D. CO is getting redused

Answer

To determine which substance is getting reduced in the reaction \( \text{ZnO} + \text{C} \rightarrow \text{Zn} + \text{CO} \), we need to analyze the oxidation states of the elements involved in the reaction.

### Step-by-Step Solution:

1. **Identify the Reactants and Products**:
The reactants are Zinc Oxide (ZnO) and Carbon (C). The products are Zinc (Zn) and Carbon Monoxide (CO).

2. **Assign Oxidation States**:
- In Zinc Oxide (ZnO), the oxidation state of Zinc (Zn) is +2, and the oxidation state of Oxygen (O) is -2.
- In elemental Carbon (C), the oxidation state is 0.
- In Zinc (Zn), the oxidation state is also 0.
- In Carbon Monoxide (CO), the oxidation state of Carbon (C) is +2, and Oxygen (O) remains -2.

3. **Determine Changes in Oxidation States**:
- For Zinc: The oxidation state changes from +2 (in ZnO) to 0 (in Zn). This indicates a decrease in oxidation state, which is characteristic of reduction.
- For Carbon: The oxidation state changes from 0 (in C) to +2 (in CO). This indicates an increase in oxidation state, which is characteristic of oxidation.

4. **Identify the Substance Being Reduced**:
Since the oxidation state of Zinc decreases from +2 to 0, Zinc Oxide (ZnO) is the substance that is being reduced in this reaction.

### Final Answer:
The substance getting reduced is **Zinc Oxide (ZnO)**.
