If 5 moles of kul at 40oc is combined with 4 moles of kus, Ask an Expert

Academics

If 5 moles of Ku(l) at 40oC is combined with 4 moles of Ku(s) at 8oC and allowed to come to thermal equilibrium, what phases will be present and what will be the final temperature? Assume the process is adiabatic and at constant pressure. State any and all other assumptions you make.

Phase ? H298o, kJ/mol         Cp298, J/mol.K
Ku(l)          28.43                           33.59
Ku(s)         47.21                            75.48

The freezing point of Ku is 25.00oC
