ΔS is positive for which one of the following reactions?
Ag+(aq) + Cl- (aq) = AgCl(s)
N2(g) + 3H2(g) = 2NH3(g)
CaO(s) + CO2(g) = CaCO3(s)
2SO3(g) = 2SO2(g) + O2(g)
H2O(l) = H2O(s)

Same question here. Which do you think move from more random to less random and why?
For example, #4 is more random because there are more moles gas on the right than left. #5 is less random because the molecules in liquid water are more free to move around than in ice where they are more or less locked in place. So dS increases in #4 and decreases in #5. dS is + for #4 and - for #5.
