Question

The following reaction occurs at 500 K. Arrange them in the order of increasing tendency to proceed to completion.
(I) $H_{2} (g) + I_{2} (g) ⇌ 2 H I (g); K_{c} = 1.8 \times 10^{- 3}$
(II) $N_{2} O_{4} ⇌ 2 N O_{2} (g); K_{c} = 3 \times 10^{- 3}$
(III) $P C l_{5} (g) ⇌ P C l_{3} (g) + C l_{2} (g); K_{c} = 1.3 \times 10^{- 4}$
(IV) $2 S O_{3} (g) ⇌ 2 S O_{2} (g) + O_{2} (g); K_{c} = 1.3 \times 10^{- 5}$

(II) < (I) < (III) < (IV)
