Using a Table of thermodynamic data, calculate the change in Gibbs free energy for each of the following reactions. In each case indicate whether the reaction is spontaneous under standard conditions. Here are some more delta G values: N2H4 (g) = 159.4 kJ/mol, FeO (s) = -255.2 kJ/mol, FeCl3 (s) = -334 kJ/mol, H3PO4 (aq) = -1142.6 kJ/mol

(a) 2 Fe(s) + O2(g)--->2 FeO(s) kJ

(b) 2 SO2(g) + O2(g)--->2 SO3(g) kJ

(c) 4 Al(s) + 3 O2(g)--->2Al2O3(s) kJ

(d) H2(g) + Cl2(g)--->2HCl(g) kJ
