Given the provided reactions and ΔH values, calculate (ΔH) for the following reaction 4NH3 (g) + 5O2 (g) ==> 4NO (g) + 6H2O (g) . Also, determine the ratio of the bond enthalpy of N=O to O=O.
(ΔH N-H = 391, ΔH O=O = 495, ΔH O-H = 463 KJ. Mol-1 )1)3NO2(g) + H2O (g) ==> 2 HNO3 (aq) + NO (g) ΔH1= -71.3 KJ2)NH4NO3(s) ==> 4N2O (g) + 2 H2O (g) ΔH2 =-125.2 KJ3)3NO(g) ==> N2O (g) +... more
