1-Calculate the equilibrium constant at 17 K for a reaction with ΔHrxno = 10 kJ and ΔSrxno = -100 J/K. (Don't round unil the end. Using the exponent enlarges any round-off error.) 2-Calculate the equilibrium constant at 103 K for the thermodynamic data in the previous question. Notice that Keq is larger at the larger temperature for an endothermic reaction.
