Compute the overall enthalpy change for the reaction

Reference no: EM13233967

For potassium, the enthalpy of sublimation is 89 kJ/mol, and the first ionization energy is 419 kJ/mol. The bond dissociation energy of Br2(g) is 193 kJ/mol, and the electron affinity of bromine is -325 kJ/mol. The enthalpy of vaporization of Br2 (l) is 31 kJ/mol. The lattice energy of KBr is -682 kJ/mol. Calculate the overall enthalpy change for the reaction:

K(s) + 1/2 Br2 (l) -> KBr(s)
