Thermodynamic analysis at different temperatures^a.

Temperature (°C)	ln kd	ΔG° (kJ mol−1)	ΔH° (kJ mol−1)	ΔS° (J mol−1 K−1) × 10−2	R 2
20	−0.49	1.24	−3.62	−1.64	0.982
30	−0.56	1.33			0.986
40	−0.63	1.49			0.988
50	−0.71	1.64			0.979
60	−0.77	1.75			0.983
70	−0.82	1.86			0.986

^aWhere, k_d = thermodynamics equilibrium constant; ΔG° = Gibbs function; ΔH° = standard enthalpy change and ΔS° = standard entropy change.
