The lattice enthalpy of licl is positive
Splet21. okt. 2024 · Lattice Energy is directly proportional to the Charge on ion and inversely proportional to radius of atom . Now in between NaCl and CsCl the radius of Cs+ is way more than Na+ , even though CsCl is more ionic but still radius is more and hence the lattice energy is less . It can also be explained using Kapustinskii Equation Share Splet23. jul. 2024 · Lattice enthalpy value from ∆ H0(5) is written with a reversed sign. ∴ Lattice enthalpy of NaCl = +788.0 kJ mol-1. Why is lattice enthalpy of NaCl negative? As an example, the lattice energy of sodium chloride, NaCl, is the energy released when gaseous Na+ and Cl– ions come together to form a lattice of alternating ions in the NaCl crystal.
