If 1.0 mole of I₂ is introduced into 1.0 litre flask at 1000 ~K , at equilibrium ( K _ c =10⁻⁶ ), which one is correct?
Options
- A[ I ₂( ~g ) ]> [ I ⁻( g ) ]
- B[ I ₂( ~g ) ]< [ I ⁻( g ) ]
- C[ I ₂( ~g ) ]= [ I ⁻( g ) ]
- D[ I ₂( ~g ) ]= 1 2 [ I ⁻( g ) ]
Correct answer
B. [ I ₂( ~g ) ]< [ I ⁻( g ) ]
Step-by-step solution
K_ C = (2 x)² (1-x) =10⁻⁶ It shows that (1-x)<2 x
