Question 1

Assume a heteronuclear diatomic molecule, AB, forms a one-dimensional crystal by lining up along the x-axis. Also assume that each molecule can only have one of six possible orientations, corresponding to atom A facing in either the positive or negative direction along the x-, y-, or z-axis. If the molecules are arranged randomly in the six directions, the molar entropy at absolute zero should be
◦ 0.
◦ R ln 66.
◦ R ln 6.
◦ R ln 6!

Question 2

The Boltzmann formula is S = k ln W. A perfect crystal has a molar entropy of 0 at absolute zero because
◦ k = 1.
◦ W = 0.
◦ W = 1.
◦ W = NA.
