3.  Consider the following hypothetical reaction (at 308 K). Standard free energies, in kJ/mol, are given in parentheses. What is the value of the equilibrium constant for the reaction at 308 K?

(b) (5%) The entropy of change for the isolated system upon freezing includes the entropy change of the surrounding as the entropy change of the water. Since the heat capacity of surrounding is large, the heat evolved by the water on freezing us absorbed by the surrounding with only an infinitesimal change in temperature. Calculate the entropy change of the surrounding! What is the change in the entropy of the universe?
