Question:

Using data from Table 5G.2 and standard graphing software, determine the standard enthalpy and entropy of the reaction N2O4(g) → 2 NO2(g) and estimate the N—N bond enthalpy in N2O4. How does this value compare with the mean N—N bond enthalpy in Table 4E.3?

TABLE 4E.3 Mean Bond Enthalpies AHB/(kJ. mol) Bond C-H C-C C=C CC* C-F C-CI C-Br 412 348 612 518 837 360 743TABLE 5G.2 Equilibrium Constants for Various Reactions T/K* Reaction H(g) + Cl(g) 2 HCl(g) H(g) + Br(g) 2
