As a substance changes phase from gas to liquid to solid:
1 The spacing between molecules increases.
2 Its density generally increases.
3 The spacing between molecules is not affected.
4 It undergoes a chemical change.

Compare the equilibrium constants for the systems shown in the table. which favors products the most? which favors products the least? rank these systems in order from most to least in terms of favoring products rather than reactants. d > b > a > c c > a > b > d b > c > d > a a > d > c > b
