In a closed system containing three different gases as shown, X2 + Y2 2XY. Choose the TWO things that MUST happen as the volume of the system is decreased at constant temperature. 1) The relative concentrations of each gas must change. 2) The concentration of each gas will increase. 3) The relative concentrations of each gas must remain constant. 4) The concentration of each gas will not change.

3) The relative concentrations of each gas must remain constant.

4) The concentration of each gas will not change.

Explanation:

For the equilibrium system:

X₂ + Y₂ ⇄ 2XY,

The no. of moles of gases in each side is constant; there is 2 moles of gases at reactants side and 2 moles of gases at products side.

So, changing the volume will not affect on the equilibrium system.

So, the right choice is:

3) The relative concentrations of each gas must remain constant.

4) The concentration of each gas will not change.
