Concept:

Problem: Using the data in the figures above calculate delta E for the reaction Na(g)+ Cl(g) →  Na+(g)+ Cl-(g) in kJ/mol

FREE Expert Solution

Recall that:

  • Ionization energy →  energy in losing e-
  • Electron affinity → energy in gaining e-


Na(g) →  Na+(g) + 1e-  → First ionization energy, IE

Cl(g) +  1e- Cl-(g)    → electron affinity, EA

                                                                                        

Na(g) + Cl(g  Na+(g) + Cl-(g)                ΔE = IE + EA 


E=IE+EA
