Question

X2(g) + Y2(g) ⇋ 2XY(g) reaction was studied at a certain temperature. In the beginning 1 mole of X2 was taken in a one litre flask and 2 moles of Y2 was taken in another 2 litre flask and both these containers are connected so equilibrium can be established. What is the equilibrium concentration of X2 and Y2? Given Equilibrium concentration of [XY] = 0.6 moles/litre.

Options

A.
B.
C.(1 - 0.3), (2 - 0.3)
D.(1 - 0.6), (2 - 0.6)

Solution

X2   +   Y2   ⇋   2XY
- x      - x      2x        2x = 0.6    ⇒   x = 0.3
[x2] = - 0.3        [y2] = - 0.3
Therefore, (A) option is correct.
