The exhaust from jet aeroplanes contains nitric oxide, which can destroy the ozone layer.(T/F)

Answer

To determine whether the statement "The exhaust from jet aeroplanes contains nitric oxide, which can destroy the ozone layer" is true or false, we can analyze the components involved and their interactions.

### Step-by-Step Solution:

1. **Identify the Components**:
- The exhaust from jet aeroplanes contains various gases, including nitric oxide (NO).

2. **Understand the Role of Nitric Oxide**:
- Nitric oxide (NO) is a nitrogen oxide that can be formed during combustion processes, such as those occurring in jet engines.

3. **Interaction with Ozone**:
- In the stratosphere, nitric oxide can react with ozone (O3). The reaction can be represented as:
\[ \text{NO} + \text{O}_3 \rightarrow \text{NO}_2 + \text{O}_2 \]
- Here, nitric oxide reacts with ozone to form nitrogen dioxide (NO2) and oxygen (O2).

4. **Impact on the Ozone Layer**:
- The depletion of ozone (O3) in the stratosphere is significant because ozone plays a crucial role in protecting life on Earth from harmful ultraviolet (UV) radiation.
- The conversion of ozone into nitrogen dioxide (NO2) reduces the amount of ozone available in the stratosphere, thus contributing to ozone layer depletion.

5. **Conclusion**:
- Since nitric oxide from jet exhaust can indeed react with ozone and contribute to its destruction, the statement is true.

### Final Answer:
**True** - The exhaust from jet aeroplanes contains nitric oxide, which can destroy the ozone layer.
