Question
1 mole each of H2(g) and I2(g) are introduced in a 1L evacuated vessel at 523K and equilibrium
H2(g) + I2(g) ⇋ 2HI (g) is established. The concentration of HI(g) at equilibrium :
H2(g) + I2(g) ⇋ 2HI (g) is established. The concentration of HI(g) at equilibrium :
Options
A.Changes on changing pressure.
B.Changes on changing temperature.
C.Changes on changing volume of the vessel.
D.Is same even if only 2 mol of HI (g) were introduced in the vessel in the begining.
Solution
H2(g) + I2(g) ⇋ 2HI (g)
(A) For changing pressure volume has to be changed, though number of moles of HI(g) do not get changed but its concentration will get changed.
(B) Temperature change will change KP and hence concentration.
(C) Volume change will change concentration, not the number of moles.
(D) Same equilibrium will be attained from either direction.
(E) Catalyst does not change equilibrium concentrations.
