The enthalpy change at 298 K for this reaction is ΔHorxn = -196.6 kJ/mol. Under the same conditions, the entropy change for the reaction is ΔSorxn = -189.6 J/mol-K.
Calculate the value of Keq for this reaction at 1936 K. Assume that ΔHorxn and ΔSorxn are the same at 1936 K as they are at 298 K. Use R = 8.314 J/K for the value of the gas constant.
a) At this temperature, Keq = 2.52e-05.
b) At this temperature, Keq = 3.61e+24.
c) At this temperature, Keq = 6.03e+03.
d) At this temperature, Keq = 9.89e-01.
e) At this temperature, Keq = 3.98e+04.
