The amino acid glycine can dimerize, meaning that two glycine molecules can form

Question

The amino acid glycine can dimerize, meaning that two glycine molecules can form a bound-state (called glycylglycine). From the thermodynamic data given below find the change in entropy Delta S per mole associated with the dimerization reaction 2 Glycine rightarrow Glycyglycine + H2O as well as the Delta S (surroundings) and Delta S (system+surroundings) Enthalpy of formation DeltaHf (kJ/mol): Glycine -537.2 Glycylglycine -746 Water -258 Third-Law Entropy Sm(J/K/mol) Glycine 103.5 Glycylglycine 190 Water 70 Verify the second lawof Thermodynamics for Delta (system + surroundings).
