). The equations describing the excess solution thermodynamic functions can be presented as [ 24 , 27 , 28 ]: (21) (22) (23) (24) (25) (26) (27) (28) where ϕ and γ are osmotic and activity coefficients, respectively; and are the partial molar
phenomenon remain in quest. With a view to ascertain the behaviour of eutectic phenomenon in the phase equilibria, excess thermodynamic functions are thought to be the best tool to reveal the molecular interactions between the binary condensed phases
equation Excess thermodynamic functions The deviation from the ideal behavior can best be expressed in terms of excess thermodynamic functions, namely, excess free energy ( g E ), excess enthalpy ( h E ), and excess
Thermal and physico-chemical studies on binary organic eutectic systems
4-Aminoacetophenone with benzoin and 4-nitrophenol
.27 The deviation from the ideal behavior can best be expressed in terms of excess thermodynamic functions, namely, excess free energy ( g E ), excess enthalpy ( h E ), and excess entropy ( s E ) which give more quantitative idea about the nature of
thermodynamic characteristics and interpret them in terms of physical chemistry, to calculate the standard thermodynamic functions C p 0 (T), H °( T ) − H °(0), S °( T ) − S °(0) and G °( T ) − H °(0) over the temperature range from T → 0 to (550–580) K
functions, g ( α ). The activation energy, E , and pre-exponential factor, A , were estimated. The transition state thermodynamic functions, Δ H *, Δ G * and Δ S *, were calculated via the activated complex theory. Experimental
) and thermodynamic functions (Δ H ∗, Δ G ∗, and Δ S ∗) via the Kissinger method is reported on the basis of thermal analysis techniques. To the best of our knowledge, such a facile and acetone-mediated synthesis route, kinetic and thermodynamic studies
by the AC and DSC techniques. Two special thermal phenomena were discovered and the mechanism was deduced. The temperature, T trs , molar enthalpies, Δ trs H m , molar entropies, Δ trs S m , of the phase transitions and thermodynamic functions, [ H T
Introduction Studies involving the determination of thermodynamic functions as a function temperature have gained importance in view of the insight they provide about systems behavior at micro level at the temperature studied
2 O 6 ·4H 2 O was interpreted by the Kissinger method [ 22 ]. The kinetic ( E a , ln A ) and thermodynamic functions (Δ H ≠ , Δ S ≠ , Δ G ≠ ) of the decomposition reaction of MnV 2 O 6 ·4H 2 O are discussed for the first time
