Figure : Thermodynamic cycle for enthalpy changes between the ideal gas phase, the solution, and the solid phase at room temperature (298 K, blue boxes) and a different temperature (T , red boxes), used to compute ∆H diss,T (bold font). In the boxes, the phase, the temperature, and the reference state used to calculated the phase change are indicated. The shaded boxes indicate the solution, i.e. the presence of a solvent.
