Calculate the standard change in Gibbs free energy for the following reaction at 25 °C.
3NO2(g)+H2O(l)--> 2NHO3(l)+NO(g)
Calculate the standard change in Gibbs free energy for the following reaction at 25 °C.
3NO2(g)+H2O(l)--> 2NHO3(l)+NO(g)
Calculate the standard change in Gibbs free energy for the following reaction at 25 °C.
3NO2(g)+H2O(l)--> 2NHO3(l)+NO(g)
Solution
The (delta)G °f values:
NO2 gas = 51.84 kJ/mol
H2O liquid = -237.13 kJ/mol
NO gas = 86.71 kJ/mol
(delta)G °f = -79.9 kJ/mol for pure concentrated liquid nitric acid.
Balanced equation that I came up with is:
3 NO2 (g) + H2O (l) ------> 2 HNO3 (l) +NO (g)
dG 0 = 8.52 KJ
