Question

The equilibrium constant for the reaction w + x ⇋ y + z is 9. If one mole of each of w and x are mixed and there is no change in volume, the number of moles of y for formed is

Options

A.0.10
B.0.50
C.0.75
D.0.54

Solution


              W    +    X   ⇋  Y    +    Z,    K = 9
Initial       1            1                0             0   
At eq.  1 - x       1 - x              x              x
K = 9 = 
∴ x = 0.75
Moles of y = x = 0.75
