1) Calculate the equilibrium constant at 138 K for the
thermodynamic data in the previous question.
Notice that Keq is larger at the larger temperature for
an endothermic reaction.
2) Endothermic reaction; increase in
entropy
Calculate the equilibrium constant at 40 K for a reaction with
ΔHrxno = 10 kJ and
ΔSrxno = 100 J/K.
