Explanation The required reaction is given below. 2 H C l ( g ) + I 2 ( s ) ⇌ 2 H I ( g ) + C l 2 ( g ) , K = 3.5 × 10 − 32 The expression for equilibrium constant for the above reaction can be written as shown below, K = ( P H I ) 2 ( P C l 2 ) ( P H C l ) 2 Given that, the initial partial pressure of H C l is 0.012 b a r . An equilibrium table can be set up as given below. C o m p o s i t i o n ( b a r ) H C l H I C l 2 I n i t i a l p r e s s u r e 0.012 0 0 C h a n g e i n p r e s s u r e − 2 x + 2 x + x E q u i l i b r i u m p r e s s u r e 0.012 − 2 x 2 x x Now, these values in the fourth row can be inserted in the equilibrium constant expression as shown below. K = ( 2 x ) 2 × ( x ) ( 0.012 − 2 x ) 2 By assuming x ≪ 0.012 , it can be written that 0.012 − x ≈ 0.012 . Now, the above equilibrium expression can be solved for x . K = ( 2 x ) 2 × ( x ) ( 0.012 − 2 x ) 2 ≈ K = ( 2 x ) 2 × ( x ) ( 0
