Question

Suggest a reason for the difference in lattice enthalpy between calcium oxide and iron(ii) oxide

Answer 1

Answer:

The Fe^2+ ion (0.076 nm) is markedly smaller than the Ca^2+ ion (0.099 nm). So the charge/size ratio is larger; so the forces of attraction are greater and the lattice enthalpy is greater.
