Production of multi strange hadrons like cascade (Ξ) and omega(Ω) baryons are studied using rate equation at Large Hadron Collider (LHC) energy. The rate equations for Ξ, Ω are solved simultaneously with other strange hadrons in an expanding medium. The results for Ξ and Ω are compared with the data obtained from Pb-Pb collisions at √sNN = 2.76 TeV from ALICE experiments. The ratio of yields of Ξ and Ω to π are analysed with various initial conditions and compared with the experimental observations made for various charge particle multiplicities. The chemical freezeout of strange hadrons(Lambda, Sigma and Kaon) are also studied comparing the expansion rate of the medium with scattering rates of these species.
