Based upon eqn (12), the expected isometric molar heat capacity becomes:
The fit for the isometric molar heat capacity ([C.sub.v]) based upon eqn.
As previously stated, this author [1] understands that a limitation for the isometric molar heat capacity being defined by eqn (10) was the gas being sufficiently dilute, i.e.
The results of the molar heat capacity and thermodynamic functions of ([H.sub.T] - [H.sub.298.15]), ([S.sub.T] - [S.sub.298.15]), and ([G.sub.T] - [G.sub.298.15]) are obtained and listed in Table 3 with a temperature of 5 K interval.
The molar heat capacity of LiB5O8-5H2O obeys a polynomial of [C.sub.p,m] (J x [mol.sup.-1] x [K.sup.-1]) = 396.79376 + 35.87528[T - ([T.sub.max] + [T.sub.min])/2]/[([T.sub.max] - [T.sub.min])/2] + 0.16494{[T - ([T.sub.max] + [T.sub.min])/2]/[([T.sub.max] - [T.sub.min])/2]}2 + 8.3083{[T - ([T.sub.max] + [T.sub.min])/2]/[([T.sub.max] - [T.sub.min])/2]}3.

This implies a molar heat capacity [C.sub.[upsilon]] =7NkT/2 = 29.3 J/(mol*K).
For most temperature regimes, the heat capacity of gases remains fairly constant, hence equation (11) can be rewritten in terms of the isometric molar heat capacity ([C.sub.[upsilon]]), i.e.
where [S.sub.o.sup.o] is the standard entropy at T = 25[degrees]C and [c.sup.o.sub.p] is the molar heat capacity.
