The neutralization of a strong acid and strong base has an enthalpy change, ∆H°, = -55.9 kJ/mol. The net ionic equation for this reaction is H⁺(aq) + OH⁻(aq) ⇌ H₂O(l) which is the reverse of the autoionization of water, and therefore ∆H° for the autoionization of water = +55.9 kJ/mol. Kw for the autoionization of water is 1.0 × 10⁻¹⁴ at 25°C. Distilled water has a [H⁺] = 1.0 × 10⁻⁷ M and a neutral pH of 7.0. Calculate the neutral pH of distilled water at 95°C.
Given these reactions and their AG° values,
COCI2(g) + 4NH3(g) → CO(NH₂)2(s) + 2NH4CI(s), AGº
= -332.0 kJ
COCI2(g) + H₂O(l) → CO₂(g) + 2HCI(g), AG° = -141.8
kJ
NH3(g) + HCI(g) → NH4CI(s), AG° = -91.96 kJ
Calculate the value of AG° for the reaction,
CO(NH2)2(s) + H₂O(l) → CO₂(g) + 2NH3(g)
AG° =
kJ
H8.
If the value of k for a reaction is 1 x 1050, which side of the reaction is favored?
