Answer»

Consider the following reactions:

(a) $H^{+} (a q) + O H^{-} (a q) \to H_{2} O (l) Δ H = - x_{1} k J m o l^{- 1}$

(b) $H_{2} (g) + \frac{1}{2} O_{2} (g) \to H_{2} O (l) Δ H = - x_{2} k J m o l^{- 1}$

(d) $C_{2} H_{2} (g) + \frac{5}{2} O_{2} (g) \to 2 C O_{2} (g) + H_{2} O (l) Δ H = x_{4} k J m o l^{- 1}$

Enthalpy of formation of $H_{2} O (l)$ is
