Question

Write the increasing order of lattice energy in kcl, nacl, licl, rbcl

Answer 1

Heya...

Lattice energy is inevresely proportional to the radius of cation or anion.
therfore, Cs has the largest radii and hecne would have low lattice energy and Li being smaller in size would have the largest Lattice enrgy.Hence the order in increasing would be:LiCl>NaCl>kcl>RbCl>CsCl

Hope it helps
