Problem: Consider the following reaction at 225K:
2Cu2O (S) → 4 Cu (S) + O2 (g)
In one of your laboratory experiments, you determine the equilibrium; you determine the equilibrium constant for this process, at 225, is 7.048E-72. You are given a table of data that indicates the standard heat of formation (ΔHo Form) of Cu2O is -170 kJ/mol. Based on this information, what is the standard entropy change (ΔSorxn) for this reaction at 225K?
