Question

Ozone reacts with $H_2{O}_2$ to give oxygen. One volume of ozone gives:

• A. one volume of oxygen
• B. half volume of oxygen
• C. three volumes of oxygen
• D. two volumes of oxygen

Answer 1

The correct option is D two volumes of oxygen

The balanced reaction between $H_2{O}_2$ and $O_3$ is as follows:

$H_2{O}_2+O_3\to H_{2}O+2O_2$

So, one volume of ozone gives $2$ volumes of oxygen.

Option D is correct.
