3. Tenorite [CuO(s)] and azurite [Cu3(CO3)2(OH)2(s)] dissolve according to the following reactions: CuO(s)+2H+(aq)Cu3(CO3)2(OH)2(s)+4H+(aq)Cu2+(aq)+H2O(l)3Cu2+(aq)+2CO2(g)+3H2O(l) Using the data in the table below, calculate the standard free energy change and the equilibrium constant for each reaction at 298.15K and 0.101MPa ( 1atm).
