The globular to random coil transition temperature for a polymer P in a dilute aqueous solution containing 0.05 mol L−1 of ligand L is 37 oC and 26 oC in the solution containing 0.08 mol L−1 of the ligand. (i) Calculate the molar enthalpy of transition if • one molecule of L binds to one molecule of globular polymer P, • four molecules of L bind to one molecule of globular polymer P. Assume that L does not bind to random coil polymer (ii) Calculate the transition temperature in 0.1 mol L−1 solution of the ligand L if one molecule of L binds to one molecule of globular polymer P. Assume that L does not bind to random coil polymer.

Question
The globular to random coil transition temperature for a polymer P in a dilute aqueous solution containing 0.05 mol L−1 of ligand L is 37 oC and 26 oC in the solution containing 0.08 mol L−1 of the ligand.
(i) Calculate the molar enthalpy of transition if
• one molecule of L binds to one molecule of globular polymer P,
• four molecules of L bind to one molecule of globular polymer P.
Assume that L does not bind to random coil polymer
(ii) Calculate the transition temperature in 0.1 mol L−1 solution of the ligand L if one molecule of L binds to one molecule of globular polymer P.
Assume that L does not bind to random coil polymer.
