The literature value for ∆H is 34.89 kJ/mol,2 and the literature value for ∆S is 0.1156 kJ mol-1 K-1.3 Percent Error was calculated with ∆H having a percent error of 15.7% and ∆S having a percent error of 3.81%. Since the solubility is decreasing with temperature, there will be more solid present as the reaction continues. The ∆H value was found to be 29.46 kJ mol-1, and ∆S was found as 0.120 kJ mol-1. This will give the -∆S value.
