Chapter 3.9, Problem 3.21P
Calculate the net energy change in kilojoules per mole that takes place on formation of KF(s) from the elements: K(s) + 1/2 F2(g) → KF(s). The following information is needed:
Heat of sublimation for K(s) = +89.2 kJ/mol
Electrostatic interactions in KF(s) = –821 kJ/mol
Eea for F(g) = –328kJ/mol
Ei;for K(g) = +418.8 kJ/mol
