Answer the following questions related to H2O. Substance ΔG°f at 298K(kJ/mol)
H2O(l) −237.2
H2O(g) −228.4

(a) Using the information in the table above, determine the value of ΔG° at 298K for the process represented by the equation H2O(l)⇄H2O(g).

Question 2
(b) Considering your answer to part (a), indicate whether the process is thermodynamically favorable at 298K. Justify your answer.

Question 3
(c) Considering your answer to part (b), explain why H2O(l) has a measurable equilibrium vapor pressure at 298K.

Question 4
Water vapor can be produced in two different processes, as represented below.

Process 1 Process 2
H2O(s)⇄H2O(g) H2O(l)⇄H2O(g)
(d) In terms of concepts of entropy and the particle-level structure of the different phases of water, explain why the change in entropy, ΔS, is greater for process 1 than for process 2.

Two nitro no2 groups are chemically bonded to a patch of surface. they can't move to another location on the surface, but they can rotate (see sketch at right). it turns out that the amount of rotational kinetic energy each no2 group can have is required to be a multiple of ε, where =ε×1.010−24 j. in other words, each no2 group could have ε of rotational kinetic energy, or 2ε, or 3ε, and so forth — but it cannot have just any old amount of rotational kinetic energy. suppose the total rotational kinetic energy in this system is initially known to be 32ε. then, some heat is removed from the system, and the total rotational kinetic energy falls to 18ε. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.
