To an equilibrium mixture of 2SO(2) (...

To an equilibrium mixture of
` 2SO_(2) (g) + O_(2) (g) hArr 2 SO_(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 ?

A

The concentration of the three gases is unchanged

B

The concentration of sulphur trioxide increases

C

The number of moles of sulphur trioxide increases

D

The concentration of sulphur dioxide increases

Text Solution

Verified by Experts

The correct Answer is:
A
As volume remains constant, the concentration of the three gases will remain unchnged on adding helium.
