$\Delta$ $H_{solute}$ corresponds to lattice energy.
$\Delta$ $H_{solute}$ is the energy required to break apart a solute in order to make it dissolve with a solvent. Lattice energy is the energy required to break up a ionic compound. Therefore, $\Delta$ $H_{solute}$ can be interpreted as lattice energy when the solute is an ionic compound.
