Question

Employing the following data (at 25ºC):

and assuming ideal behaviour, calculate the ΔH and ΔU of the following
reactions:

Employing the following data (at 25°C):
1/2H, (g)+1/20, (g)→ HO (g) AH=10.06 kcal mol"1
A,H=-57.80 kcal mol"
H, (g)+1/20, (g)→H,O (g)
H, (g)→ 2H (g)
AH=104.178 kcal mol-
0, (g) →20 (g)
AH=118.318 kcal mol-
assuming ideal behaviour, calculate the AH and AU of the following
ctions:
HO (g) →H (g)+O (g)
H,0 (g) → 2H (g) +O (g)
H,0 (g) →H (g)+HO (g)

Expert Solution

Step 1

Given:

$(\frac{1}{2} H_{2} (g) + \frac{1}{2} O_{2} \to HO (g) ∆ H = 10.06 kcal . {mol}^{- 1}) - - - eqn (1) (H_{2} (g) + \frac{1}{2} O_{2} \to H_{2} O (g) ∆ H = - 57.80 kcal . {mol}^{- 1}) - - - eqn (2) (H_{2} (g) \to 2 H (g) ∆ H = 104.178 kcal . {mol}^{- 1}) - - - eqn (3) (O_{2} (g) \to 2 O (g) ∆ H = 118.318 kcal . {mol}^{- 1}) - - - eqn (4)$
