The equilibrium between water and its vapour, in an open-vessel

Solution:

In an open vessel, the water vapour diffuse into air and therefore, the concentration of water vapour above water surface is negligible.
The reverse process of condensation of vapour into liquid form is almost absent.
Therefore, evaporation process continues, till the entire water changes into vapour form.
Therefore, in an open vessel, the water vapour system is never in equilibrium.
Finally the whole water will diffuse into air as water vapour.

Solution:

NH3(g) + 3 4 O2(g) → 1/2 N2(g) + 3/2 H2O (l)
T = 298 K
ΔH = - 382.64 kJ mol-1
ΔS = - 145.6 JK-1 mol-1
= - 0.1456 kJ K-1 mol-1
ΔG = ΔH - TΔS
= -382.64 kJ mol-1 - (298 K) x (0.1456 k JK-1 mol-1)
= -382.64 kJ mol-1 + 43.3888 kJ mol-1
= -339.25 kJ mol-1 ≅ - 339.3 kJmol-1
