On the basis of
G for each of the following reactions, decide whether the reaction is spontaneous or nonspontaneous as written. Or, if you expect an equilibrium mixture with significant amounts of both reactants and products, say so.
a. SO2(g) + 2H2S(g) → 3S(s) + 2H2O(g);
∆Go = 91 kJ
b. 2H2O2(aq) → O2(g) + 2H2O(l);
∆Go = 211 kJ
c. HCOOH(l) → CO2(g) + H2(g);
∆Go = 119 kJ
d. I2(s) + Br2(l) → 2IBr(g);
∆Go = 7.5 kJ
e. NH4Cl(s) → NH3(g) + HCl(g);
∆Go = 92 kJ
