Let the equilibrium concentrations of iodine and chlorine be

x

M each.

The initial concentrations of

I Cl, I_{2}

and

C l_{2}

are 0.78 M, 0 M and 0 M respectively.

The equilibrium concentrations of

I Cl, I_{2}

and

C l_{2}

are 0.78-2x, x and x M respectively.

K_{c} = \frac{[ I _{2} ] [ C l _{2} ]}{[ I Cl ] ^{2}}

0.14 = \frac{x \times x}{( 0.78 - 2 x ) ^{2}}

x^{2} = 0.14 (0.78 - 2 x)^{2}

x = 0.292 - 0.748 x

x = 0.167

Hence the equilibrium concentrations are,

[I_{2}] = 0.167 M

[C l_{2}] = 0.167 M

[I Cl] = 0.78 - 2 (0.167) = 0.446 M
