Note: This Quiz has a possible 20 points maximum.
On questions that require calculation, please show your work in the space provided.
If you need more space, then use the back of the paper and indicate that t
= 100.0 kJ/mol and
= 20 J/mol K for a hypothetical phase
transition. At what temperature are the two phases
in equilibrium (in other words, what is the melting
(a) 5 K
(b) 5 K
(c) 5000 K
(d) 5000 K
0 = 100 kJ/mol T 2
1. Is Srxn
> 0, = 0, or < 0 for the following reaction:
P4(g) + 6Cl2(g) 4P Cl3(g)?
(a) > 0
(b) = 0
(c) < 0
There are fewer moles of gas on the product side than
on the reactant side, so there is more order in the
products and therefore Srxn
