Consider the dimerization reaction 2 NO2(g) → N2O4(g). This reaction is exothermic, since the major chemical change is the formation of a new bond (the N-N bond). The value of ∆rH0 for this reaction carried out at a temperature of 298 K is -57.2 kJ. The standard molar capacity of N2O4(g) is Cp,m = 77.28 J/K-mol, and the standard molar heat capacity of NO2(g) is Cp,m = 37.2 J/K-mol. Given this information, what is the value of ∆rH0 for the dimerization reaction carried out at a temperature of 1298 K?
