Verified by Toppr
The reaction proceeds in forward reaction because LiF is more stable than LiI as it has higher bond disassociation energy because of small radius of both cation (Li) and anion (F).
Larger cation is stabilized by larger anion (as in this case K is stabilized by I ).
Hence,option B is correct.
