Cculate the change in enthalpy for 2lis 2hbrg rarr h2g

Question

Li(s) →Li(g) enthalpy of sublimation of Li(s) = 166 kJ/mol
HBr(g) → H(g) + Br(g) bond energy of HBr = 363 kJ/mol
Li(g) → Li+(g) + e- ionization energy of Li(g) = 520. kJ/mol
Br(g) + e- → Br-(g) electron affinity of Br(g) = -325 kJ/mol
Li+(g) + Br-(g) → LiBr(s) lattice energy of LiBr(s) = -809 kJ/mol
H2(g) → 2H(g) bond energy of H2 = 432 kJ/mol

Calculate the change in enthalpy for: 2Li(s) + 2HBr(g) → H2(g) + 2LiBr(s)
