AH°f, kJ/mol NH3(g) -46 NO(g) 90. H2O(g) -242 NO2(g) 34 Н,0() -286 HNO3(aq) -207 AH°1 = kJ AH°2 = kJ AH° - kJ Write the overall equation for the production of nitric acid by the Ostwald process by combining the preceding equations. (Water is also a product.) (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.)
