Factors affecting lattice energy If inter ionic distance decreases than attractions increases thus lattice energy increase Now in the given question the common is anion i.e Cl and as we know that cl is small in size so we have to see cationic part as cation size increases inter ionic distance increases so lattice energy decreases so order isLiCl>NaCl>kcl>RbCl>CsCl

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:
CsCl then RbCl then KCl then NaCl then LiCl.

here the size of anion is same but the size of the cation vary and the size of cation increases on moving down the group due to which the bond length b/w the ions increases and bond dissociation energy also increases thats why the order is 
licl,nacl,kcl,rbcl,cscl
