The steps to the Born-Haber cycle for RbCl are outlined. Identify each step as endothermic or exothermic. 1. sublimation of rubidium Rb(s) Rb(g) 2. dissociation of the chlorine molecule Cl₂(g) → 2Cl(g) 3. ionization of rubidium Rb(g) Rb (g) + e¯ 4. electron affinity of chlorine Cl(g) + e- Cl-(g) 5. formation of RbCl from its ions Rb+ (g) + Cl- (g) RbCl(s) The overall reaction is the formation of one mole of RbCl from its elements in their standard states. Is the overall reaction endothermic or exothermic? Rb(s) + 1/2Cl₂(g) → RbCl(s)
