Question

Calculate the standard molar entropy of CHCl₃ at 300, 400, 500, 600, 700, and 800 K. The rotational constants and vibrational constants are given in the table below.

CHCl3   (from NIST Data Tables)
Vibrational Data			Rotational Data		Electronic
Symmetry	Freq(cm-1)	degeneracy	Rotational Constants (cm-1)		gel = 1
A1	3034	1	0.11015	Sym. No.
A1	680	1	0.11015	σ = 3
A1	366	1	0.05932
E	1220	2
E	774	2
E	260	2

Compare your result at 300 K with delta S= 296.35 J / (mol-K).
