Q. To an equilibrium mixture of
$2SO_{2}(g) + O_{2}(g) \rightleftharpoons 2SO_{3}(g)$
some helium, an inert gas, is added at constant volume. The addition of helium causes the total pressure to double. Which of the following is true?

Equilibrium

Solution:

As volume remains constant, the concentration of the three gases will remain unchanged on adding helium.
