Question

Given the following free energies of formation, calculateGo for the reaction: 3NO2(g) + H2O(l) --->2HNO3(l) + NO(g)                           Gof (kJ/mol) H2O(l)                    -237.2 HNO3(l)                 -79.9 NO(g)                       86.7 NO2(g)                     51.8 Given the following free energies of formation, calculateGo for the reaction: 3NO2(g) + H2O(l) --->2HNO3(l) + NO(g)                           Gof (kJ/mol) H2O(l)                    -237.2 HNO3(l)                 -79.9 NO(g)                       86.7 NO2(g)                     51.8 H2O(l)                    -237.2 HNO3(l)                 -79.9 NO(g)                       86.7 NO2(g)                     51.8

Explanation / Answer

Go = sum of products - sum of reactants = (2*-79.9) + ( 86.7) - (3*51.8) - ( -237.2) = +8.7kj/mol
