Given that for the vaporization of benzene Hvap= 30.7 kj/mol and Svap= 87.0 J(K * mol) , calculate Delta G (in kJ/mol) for the vaporization of benzene at 13 Celcius.

Question

Given that for the vaporization of benzene  Hvap= 30.7 kj/mol and  Svap= 87.0 J(K * mol) , calculate Delta G (in kJ/mol) for the vaporization of benzene at 13 Celcius.

DrBob222 · Answer

dG = dH - TdS dG = 30.7 - (273+13)*0.087 = ? in kJ/mol.Note that dS is in J/mol*K so I changed that to kJ/mol*K
