Question 1

Calculate the lattice energy for MgO(s) using a Born-Haber cycle and the following information:

MgO(s) → Mg2+(g) + O2-(g)?
Mg(s) → Mg(g)+147.1 kJ/mol
Mg(g) → Mg+(g) + e-+737.8 kJ/mol
Mg+(g) → Mg2+(g) + e-+1451 kJ/mol
1/2 O2(g) → O(g)+249.0 kJ/mol
O(g) + e- → O-(g)-141.1 kJ/mol
O-(g) + e- → O2-(g)+798.0 kJ/mol
Mg(s) + 1/2 O2(g) → MgO(s)-601.8 kJ/mol

◦ +3844 kJ/mol
◦ +2444 kJ/mol
◦ +4108 kJ/mol
◦ +1842 kJ/mol

Question 2

Calculate the energy change in kJ/mol for the reaction using the following information:

Li(g) → Li+(g) + e-+520 kJ/mol
F(g) + e- → F-(g)-328 kJ/mol

◦ +848 kJ/mol
◦ -192 kJ/mol
◦ -848 kJ/mol
◦ +192 kJ/mol
