On heating ozone, its volume.

Options

A. Increase to `1.5` times
B. Decreases to half
C. Remain uncharged
D. Becomes double

Explanation

To solve the question regarding the change in volume of ozone when heated, we can follow these steps:

### Step 1: Understand the Reaction
When ozone (O₃) is heated, it decomposes into oxygen (O₂). The balanced chemical equation for this reaction is:
\[ 2 \text{O}_3 \rightarrow 3 \text{O}_2 \]

### Step 2: Analyze Moles of Gas
From the balanced equation, we see that 2 moles of ozone produce 3 moles of oxygen. Therefore, if we start with 1 mole of ozone, it will produce:
\[ \frac{3}{2} \text{ moles of O}_2 \]

### Step 3: Relate Moles to Volume
According to Avogadro's law, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles of the gas. Therefore, if we increase the number of moles of gas, the volume will also increase.

### Step 4: Calculate the Volume Change
Starting with 1 mole of ozone, upon heating, we produce:
\[ 1 \text{ mole of O}_3 \rightarrow 1.5 \text{ moles of O}_2 \]
This means the volume of gas increases from 1 mole to 1.5 moles.

### Step 5: Conclusion
Thus, the volume of the gas increases to 1.5 times its original volume when ozone is heated.

### Final Answer
The volume of ozone when heated increases to 1.5 times.
