WebThermodynamic favorability and temperature. The temperature conditions under which a process is thermodynamically favored (ΔG° < 0) can be predicted from the signs of ΔH° and ΔS°. When ΔH° < 0 and ΔS° > 0, the process is favored at all temperatures. When ΔH° > 0 and ΔS° < 0, the process is favored at no temperature. WebThis technique has been widely used in characterizing the stability of proteins in their native form by measuring the amount of heat required to denature a particular biomolecule (e.g., protein). Generally, molecules with higher thermal transition midpoint (T m) are considered more stable than those with lower transition midpoints.
