(8) Use values of enthalpies of formation, standard entropies, and standard molar heat capacities at constant pressure to calculate the standard reaction entropy and standard reaction enthalpy of the following reaction at both 298K and 500K. - 1/2N2(g)+3/2H2(g)NH3(g). Assume that the standard molar heat capacities at constant pressure are constant over the temperature range involved. Given the standard molar entropies (Sm) at 298K for N2(g) is 191.61J/Kmol,H2(g) is 130.684J/Kmol, and NH3(g) is 192.45J/Kmol. The standard enthalpies of formation (fH) at 298K for N2(g) is 0kJ/mol,H2(g) is 0kJ/mol, and NH3(g) is 46.11kJ/mol. Standard molar heat capacities at constant pressure (CP,m) at 298K for N2(g) is 29.125J/Kmol,H2(g) is 28.824J/Kmol, and NH3(g) is 35.06J/Kmol
