6. Define Lattice formation enthalpy

  • The enthalpy change when 1 mol. of compound is formed from its constituent elements under standard conditions. All reactants and products in their standard states
  • The standard enthalpy change when 1 mol. of solid ionic compound is formed from its gaseous ions
  • The enthalpy change which accompanies the formation of 1mol. of gaseous atoms from the element in its standard state under standard conditions

7. What is the enthalpy of hydration?

  • The standard enthalpy change when 1 mol. of gaseous atoms is converted into 1 mol. of gaseous ions each with a single negative charge
  • The standard enthalpy change when water molecules surround 1 mol. of gaseous ions
  • The standard enthalpy change when 1 mol. of solute dissolves completely in sufficient solvent to form a solution in which the molecules or ions are far enough appart not to interact with each other

8. Define the enthalpy of solution.

  • The standard enthalpy change when water molecules surround 1 mol. of gaseous ions
  • The standard enthalpy change when 1 mol. of solute dissolves completely in sufficient solvent to form a solution in which the molecules or ions are far enough appart not to interact with each other
  • The standard enthalpy change when 1 mol. of gaseous atoms is converted into 1 mol. of gaseous ions each with a single positive charge
