Desorption profiles of acids (red), bases (blue), and the resulting salt (black). Desorption energies and pre-factors for H₂O, NH₃, and HCN are obtained from Minissale et al. (2022), while the parameters for the remaining molecules are taken from Table 1. Peak desorption temperatures are indicated in the plot for each species. The desorption profile is simulated with a first-order Polanyi-Wigner equation, surface coverage of 10¹⁵ molecules cm⁻² and heating rate of 1 K century⁻¹.
