The enthalpy of tetramerization of X in gas phase (4X (g)→ X4 (g)) is -100 kJ/mol at 300 K. The enthalpy of vaporisation for liquid X and X4 are respectively 30 kJ/ mol and 72 kJ/mol respectively. ∆S for tetramerization of X in liquid phase is -125 J/Kmol at 300 K, what is the ∆ G at 300 K for tetramirization of X in liquid phase?
(A)-52 kJ/mol
(B)-89.5 kJ/mol
(C) -14.5 kJ/mol
(D) None of these
