When 100 ml of a O2 - O3 mixture was passed through turpentine,
there was reduction of volume by 20 ml. If 100 ml of such a mixture is

heated, what will be the increase in volume? [Hint: O3 is absorbed by

Show answer and solution
In the mix., volume of O3 = 20 ml, Volume of O2 = 80 ml
on heating 2O3 → 3O2

20 ml O3 will give × 20 = 30 ml O2

total volume = 80 + 30 = 110 ml

increase in volume = 110 - 100 = 10 ml.
