| Abstract: | It is emphasized that any equation of state (EOS) based on the generalized Lennard-Jones potential or the Mie potential, suffers
from two main shortcomings as pointed out by Stacey and Davis 2]. One of the shortcomings viz. the problem related to imaginary numbers for the exponents in the potential function, has been removed recently by Jiuxun
11] by using a relationship between the exponents. However, the modified EOS obtained by Jiuxun suffers from the second shortcoming
viz. it gives lower values for −B
0
B″0, an important equation of state parameter related to the second pressure derivative of the bulk modulus. Values of B
0
B″0 obtained by Jiuxun are not consistent with those reported by Stacey and Davis.
