Question

In which of the following reactions, the formation of product is favoured by decrease in temperature?
(1) $N_{2} (g) + O_{2} (g) \to 2 N O (g)$ $Δ H = 181$
(2) $2 C O_{2} (g) \to 2 C O (g) + O_{2} (g); Δ H = 566$
(3) $H_{2} (g) + I_{2} (g) \to 2 H I (g); Δ H = - 94$
(4) $H_{2} (g) + F_{2} (g) \to 2 H F (g); Δ H = - 541$

H_{2} (g) + I_{2} (g) \to 2 H I (g); Δ H = - 9.2 K J / m o l e

The heat of reaction of $I_{2} (s) \to I_{2} (g)$ is:

C (s) + O_{2} (g) ⟶ C O_{2} (g)

Δ H = - 94 K c a l

H_{2} (g) + I / 2 O_{2} (g) ⟶ H_{2} O (l)

Δ H = - 68 K c a l

C_{2} H_{5} O H (l) + 3 O_{2} (g) ⟶ 2 C O_{2} (g) + 3 H_{2} O (l)

Δ H = - 327 K c a l
