Question

1 mole each of H 2 ​ ( g ) and I 2 ​ ( g ) are introduced in a 1L evacuated vessel at 523 K and the equilibrium : H 2 ​ ( g ) + I 2 ​ ( g ) ⇌ 2 HI ( g ) is established. The concentration of HI(g) at equilibrium :

TestHub · Accepted Answer

H 2 ​ ( g ) + I 2 ​ ( g ) ⇌ 2 HI ( g ) ; K eq ​ = [ H 2 ​ ] [ I 2 ​ ] [ HI ] 2 ​ = ( 1 − x ) ( 1 − x ) 4 x 2 ​ (B) Temperature change will change K eq ​ and hence concentration. (D) Catalyst does not change equilibrium concentrations.
