Chapter 6, Problem 6.80SP

Calculate the energy change in kilojoules per mole when lithium atoms lose an electron to bromine atoms to form isolated ${\text{Li}}^{+}$ and ${\text{Br}}^{-}$ ions. [The $E_i$ for Li(g) is 520 kJ/mol; the $E_{ea}$ forBr(g) is -325 kJ/mol.] Will a lithium atom transfer an electron to a bromine atom to form isolated ${\text{Li}}^{+}\left(g\right)$ and ${\text{Br}}^{-}\left(\text{g}\right)$ ions? Explain.
