Dear friends
I m trying to find out standard enthalpy and entropy of LiBr-water solution having different concentration of LiBr at STP conditions. I have used also EES for this but when i have give input as 25 C and 101.325 kPa, EES is also enable to give answer. Is there any method by which i can find standard enthalpy and entropy of LiBr-water solution having different concentration of LiBr at STP conditions.
You may want to check the following papers:

You will find values tabulated for various concentrations of LiBr in water in the NBS Tables of Chemical Thermodynamic Properties, Journal of Physical and Chemical Reference Data, Volume 11, No. 2, 1982, Published by American Chem. Soc.,, Authors Wagman, Donald D., et al.

All formulas of LiBr water solution used concentration and temperature for calculation. Please see Feuerecker et.al and Y. Kaita equations, the first one used between 40 to 75 % & 40 to 190 C and the second one for the range 40 to 65 % & 40 to 210 C. The pressure is not one of the parameters used in the equations. In order to include the pressure within the range you can use ASHRAE charts to examine the corresponding temperature against the X & P. Finally you must use only Feuerecker et al equation to cover the 25 C condition.
