Estimation of the Standard Formation Enthalpy of Carbonates

Abstract

Abstract: An influence of bond structure factors containing ionic charge,coordination radius and electron configuration etc,on the thermodynamic property of carbonates is investigated by means of the bond parameter function CASPscale. A new method for predicting the standard formation enthalpy ΔH⁰_f of the carbonates is established,and the values of some carbonates are calculated,the results are in good agreement with the relative values from literatures.There are some H⁰_f values of the carbonates such as MgCO₃,Tb₂(CO₃)₃ etc.in literatures,which seem to be unusual and are also discussed in this paper.

Key words: Thermodynamic property, Standard formation enthalpy, Carbonate
