Calculate the corresponding standard reaction Entropy and Gibbs Free energy at 298 K for the following reactions. Use the data tables in the book. (a)Zn(s) + Cu2+(aq) ® Zn2+(aq) + Cu(s) (b)C12 H22 O11 (s) + 12 O2(g) ® 12 CO2(g) + 11 H2O(l) (c)A spontaneous process has a positive change in the entropy of the universe. Comment about the spontaneity of the processes above based on your calculations
