Rbcl lattice enthalpy

Web7. The solubility of Group 2 sulphates decreases down the group. REASON: Both enthalpy change of lattice and enthalpy change of hydration are involved. Enthalpy change of hydration decreases more than enthalpy change of lattice. So, enthalpy change of solution becomes more endothermic. Please explain the text in bold.
