The two body non-leptonic $\Lambda_b$ decays are analyzed in the HQET with factorization approximation and large $N_c$ limit. In this limit, $\Lambda_b$ and $\Lambda_c$ baryons can be treated as the bound states of chiral soliton and heavy meson, and consequently the Isgur-Wise function comes out in a straight forward manner. The results obtained remain well below their previously predicted upper limit.
