Consider the following reaction:
3 H2(g) + N2(g) 2 NH3(g)
The enthalpy change at 298 K for this reaction is Horxn = -92.38kJ/mol. Under the same conditions the entropy change for thereaction is Sorxn = -198.24 J/mol-K. Calculate the value of Gorxnat a temperature of 758 K where the reaction is under standardconditions other than the temperature. Assume that Horxn and Sorxndo not change with temperature.
a) At this temperature Gorxn = 1.50e+05 kJ/mol.
b) At this temperature Gorxn = 5.79e+01 kJ/mol.
c) At this temperature Gorxn = 5.90e+04 kJ/mol.
d) At this temperature Gorxn = -1.51e+02 kJ/mol.
e) At this temperature Gorxn = -1.50e+05 kJ/mol.
