Consider two solutes with the same lattice energy in kj/mol; however, the particles of solute a are strongly solvated by water, while those of solute b are only weakly solvated. which of the two dissolution processes is more exothermic, on a kj/mol basis? 1. cannot be answered without knowing the identities of the solutes. 2. both processes are equally exothermic. 3. it depends on the molecular weights of the solutes. 4. dissolving a in water 5. dissolving b in water
