The relationship between the enthalpy (ΔH) and entropy (ΔS) of a
reaction that is spontaneous at higher temperatures but not at lower
temperatures is +ΔH, - Δs.
Relationship between enthalpy and entropy
The relationship between enthalpy (ΔH) and entropy (ΔS) is given by Gibs free energy.
ΔG = ΔH - TΔs
When ΔH < 0 and Δs < 0, ΔG = -ve (-ΔH, - Δs) (for lower temperature)
Also, when ΔH < 0 and Δs = +, ΔG = -ve (-ΔH, +Δs) (for all temperature)
When ΔH > 0 and Δs < 0, ΔG = -ve (+ΔH, - Δs) (for higher temperature)
Thus, the relationship between the enthalpy (ΔH) and entropy (ΔS) of a
reaction that is spontaneous at higher temperatures but not at lower
temperatures is +ΔH, - Δs.
