Protein denaturations are usually irreversible but may be reversible under a narrow range of conditions. At pH 2.0, at temperatures ranging from about 40o C to 50o C, there is an equilibrium between the active form P and the deactivated form D of the enzyme trypsin: P ¡ê D. Thermodynamic values are ¥ÄH¥è =283 kJ/mol and ¥ÄS¥è =891 J/Kmol. Assume these values to be temperature independent over this narrow range. At what temperature will there be equal concentrations of P and D?
