Enthalpy of Solution vs Temperature
Enthalpy of Solution vs Temperature
(OP)
Hello,
I am looking for a simple way to describe the dependence between the enthalpy of solution (e.g carbon dioxide (g) in hot water) and temperature.
Thanks in advance,
Mike

Thank you very much.
P.S. What is the sytemabsortion?

RE: Enthalpy of Solution vs Temperature
The temperature dependence of the solubility of gases is given by the relation
where c is the number of moles of gas dissolved in a definite volume of solvent and ΔHsol is the molar heat of solution, assumed constant in the given temperature interval.
Since values of c as function of T are amply tabulated, one could solve for the molar heat of solution from:
2.303R can be replaced by 4.576, and T are in Kelvin.
