On heating ozone, its volume

On heating ozone, its volume
  1. Increases to \(1.5\) times
  2. Decreases to half
  3. Remain unchanged
  4. Becomes double

Solution

On heating ozone, we get:
\(\begin{aligned}
& \mathrm{O}_3 \xrightarrow{\Delta} \mathrm{O}_2+\frac{1}{2} \mathrm{O}_2 \\
& \therefore 1 \text { mole } \mathrm{O}_3 \text { gas gives }=1+\frac{1}{2} \\
&=\frac{3}{2} \text { moles of } \mathrm{O}_2 .
\end{aligned}\)
\(\therefore\) Volume increases to \(3 / 2\) times
