(Q75) The decomposition of gaseous nitric acid into its element is a nonspontaneous process with a value for AG°rxn of +73.5 kJ/mol for the process: HNO3(g) --> 1/2 H2 (g) + 1/2 N2 (g) + 3/2 O2 (g).

Question
(Q75) The decomposition of gaseous nitric acid into its element is a nonspontaneous process with
a value for AG°rxn
of +73.5 kJ/mol for the process:
HNO3(g) --> 1/2 H2 (g) + 1/2 N2 (g) + 3/2 O2
(g).
What is the value of AGrxn if the reaction takes place at 727°C and the partial pressures of the
gases are:
PHNO3 = 0.882 atm, PH2 = 0.102 atm, PN2 = 0.161 atm, and Po2 = 0.00318 atm.
