-Which arrows represent ΔH_{solute-solute} and ΔH_{solvent-solvent}?

Quizplus · Accepted Answer

ΔH_{solute-solute} and ΔH_{solvent-solvent} refer to the enthalpy changes associated with breaking interactions between solute particles and solvent particles, respectively. Arrows (a) and (b) typically represent these processes in a diagram of solution formation.
