Given the following information:
Li(s) → Li(g)
Li(s) = 161 kJ/mol
Heat of sublimation of
HCI(g) → H(g) + Cl(g)
Bond energy of
HCI = 427 kJ/mol
Li(g) → Li+(g) + e-
lonization energy of
Li(g) = 520. kJ/mol
CI(g) + e- → CI-(g)
Electron affinity of
Cl(g) = -349 kJ/mol
Li+(g) + Cl-(g) →→ LiC(s)
Lattice energy of
LİCI(s) = -829 kJ/mol
H2(g) → 2H(g)
Bond energy of
H2 = 432 kJ/mol
calculate the net change in energy for the
reaction 2Li(s) + 2HCI(g) → 2LİCI(s) + H2(g)
