At what temperature will the egg start to denature

Care the nomenclature critical) is employed in many other areas of physical chemistry (e.g. see pp. 50 and 189). 

If AG goes from positive to negative as the temperature alters, then clearly the value of AG will transiently be zero at one unique temperature. At this point of reaction spontaneity , the value of AG = 0. We often call this the critical temperature 7(CritjCai). 

The value of r riticai), i.e. the temperature when the reaction first becomes thermodynamically feasible, can be determined approximately from 

We will employ the thermodynamic data from Worked Example 4.12. Inserting values into Equation (4.74)  

This method yields only an approximate value of 7 (criticai) because AS and AH are themselves functions of temperature.
