Enthalpy + entropy

• Enthalpy of hydration definition - The enthalpy change when one mole of gaseous ions is dissolved in water forming one mole of aqueous ions under standard conditions
• Entropy definition - The measure of the disorder or randomness of a system.
• First electron affinity definition- The energy change when one electron is added to each atom in one mole of gaseous atoms to form one mole of gaseous -1 ions
• Enthalpy of solution definition- The enthalpy change when 1 mole of a solute is completely dissolved in water under standard conditions
• Lattice enthalpy definition - The enthalpy change when one mole of an ionic compound is formed from its gaseous ions under standard conditions
• Enthalpy change of atomisation definition - The enthalpy change when 1 mole of gaseous atoms is formed from the element in its standard state under standard conditions
• $∆Hlatt =$$∆Hf - (the rest)$
• $∆G^ θ =$$-∆S^ θT +$$∆H^ θ$
• $ΔHlatt +$$ΔHsol =$$ΔHhyd +$$ΔHhyd$
