above system at equilibrium ?

1   I 2 + I = 1 + x            
                2   I
2 = 1 2 I 3   I 2 g > >   I g      
                4  
Both   1   and   3

For equilibrium                                     I2 ↔2 IInitial                         1           - At equilibrium         1-x    2xK=[I]2[I2] =2x21-x 4x21-x = 10-6Its given that i mole of I2 is added So equilibrium concentration of I2 becomes = 1-x+1 = 2-xEquilibrium concentration of I  = 2xThus I2 >>IOption 3 is correct

Solve this: 11. For I2(g) ⇌ 2I(g), KC at 1000 K is 10-6. One mole I2 is added in a one-litre container. Which of the following expressions is correct for the above system at equilibrium ? 1 I 2 + I = 1 + x 2 I 2 = 1 2 I 3 I 2 g > > I g 4 Both 1 and 3
