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

the free gibbs energy G for total reaction is given by G of product -reactant as we know G = -nFE so total G for reaction= [86.7+ 2(-79.9)] - [(3*51.8) + (-237.2)] = 8.7 KJ/mol
