Use enthalpies of atom combination and entropies of atom combination to determine if any of the following reactions have an equilibrium constant greater than 1. Find the reaction with the greatest equilibrium constant. Find the reaction with the smallest equilibrium constant.
a) HF(aq) ? H+(aq) + F-(aq)
b) N2(g) + 3 H2(g) ? 2 NH3(g)
c) PbCl2(s) ? Pb2+(aq) + 2 Cl-(aq)
