The molecular scale drawings below represent the three phases of iodine (I₂), which is a solid at normal temperature and pressure. 

(a) In what order should the pictures be placed to put them in terms of decreasing entropy? 

(b) Assuming the pressure is the same in all three cases, in what order should they be placed to put them in order of increasing temperature? 

(c) Which picture depicts a situation in which enthalpy is the most important factor for the free energy, and in which picture is entropy the most important factor?
