what is the equillibrium constant of each of the substance in the equillibrium when concentration of ICl was 0.75M 2ICl(g)=I2+Cl2
kc=o.12

You haven't stated the problem very clearly. I assume you mean the equilibrium "concentrations" and not equilibrium constants. You have the Kc given in the problem. Also, I assume that 0.75M is (ICl) initially and not at equilibrium.
..........2ICl ==>I2 + Cl2
I.........0.75.....0.....0
C..........-2x.....x......x
E........0.75-x....x.....x

Substitute the E line nto the Kc expression and solve for x.
