Calculate the Energy Required for the Gas Phase Process Represented $\rarr$

Short Answer

Calculate the energy required for the gas phase process represented by
Na(g)+ Br(g) $\rarr$ Na⁺(g)+ Br ^- (g)
Given:
Ionization energy (Na) = 496 kJ/mol
Electron affinity (Br) = 324 kJ/mol
Electron affinity (Na) = 53 kJ/mol
