Igcse Model Questions Vol1 2017 Chemistry Question 12
Practice objective / multiple choice question 12 from the 2017 Igcse Model Questions Vol1 Chemistry examination.
The standard enthalpy change for formation of solid NaCl from its elements is \(-411\ \text{kJ mol}^{-1}\). The following data are given: sublimation of Na(s) \(+108\ \text{kJ mol}^{-1}\); first ionisation energy of Na \(+496\ \text{kJ mol}^{-1}\); bond dissociation energy of \(\mathrm{Cl_2(g)}\) \(242\ \text{kJ mol}^{-1}\); electron affinity of Cl \(-349\ \text{kJ mol}^{-1}\). Using a Born-Haber cycle, calculate the magnitude of the lattice energy of NaCl(s) in kJ mol\(^{-1}\).
