Utilizing thermodynamic data from your notes, Compute the change in Gibbs free energy for each of the subsequent reactions using Gf's. In each case indicate whether the reaction is spontaneous under standard conditions.
(a) HCl(g) + NaOH(aq) NaCl(s) + H2O(l) kJ spontaneous or nonspontaneous
(b) H2(g) + Cl2(g) 2 HCl(g) kJ spontaneousor nonspontaneous
(c) 6 Cl2(g) + 2 Fe2O3(s) 4 FeCl3(s) + 3 O2(g) kJ spontaneous or nonspontaneous
(d) Mg(OH)2(s) + 2 HCl(g) MgCl2(s) + 2 H2O(l) kJ spontaneous or nonspontaneous
