in the reaction x y gives 2z, each 1 mole is placed in 10 lit vessel and allowed to rech equilibrium.if z is 0.2 at equilibrium,kc?

              x       +         y      -------------->       2z
    t=0     0.1              0.1                                 0
t=t        0.1-x            0.1-x                               2x
At eqm. given,
2x = 0.2
x = 0.1
Hence, Kc = 4x^2/(0.1-x)^2
put x = 0.1
Kc is tending to infinite as the reactants get totally consumed.
