A reaction enthalpy of −27,756.7 J mol−1 was determined by Calvet calorimetry at 25 ◦C [10]. The reaction is highly exothermic, especially when compared to the enthalpy of the reaction between LiH and N2H4BH3 at the same temperature (−62.8 J mol−1). In fact, the bigger ...
system was thermodynamically spontaneous according to thermodynamic property calculations, including standard Gibbs energy, dissolution enthalpy, and dissolution entropy [60]. Huang et al. [61,62] further proposed introducing an HBD component with weak acidity into a ChCl-based system, which not only...
