Write a chemical equation for the formation reaction and then calculate the standard free energy of formation of each of the following compounds from the enthalpies of formation and the standard molar entropies, using ∆G◦ r = ∆H◦ r - T∆S◦ r:
(a) NH3(g)
(b) H2O(g)
(c) CO(g)
(d) NO2(g)
First calculate entropy change and enthalpy change of the reaction using thermodynamic data.
Then using formula find deltaG.
