Lattice Energy

Chemistry ⇒ Chemical Bonding and Structure

Lattice Energy starts at 11 and continues till grade 12. QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Lattice Energy. How you perform is determined by your score and the time you take. When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.

See sample questions for grade 12

Calculate the lattice energy of NaCl using the following data (all values in kJ/mol): Enthalpy of formation of NaCl = -411, Sublimation energy of Na = 108, Ionization energy of Na = 496, Bond dissociation energy of Cl₂ = 242, Electron affinity of Cl = -349. (Assume all steps are for 1 mole of NaCl.)
