Chemistry Question on Thermodynamics

Tin is obtained from cassiterite by reduction with coke Use the data given below to determine the minimum temperature (in KK ) at which the reduction of cassiterite by coke would take place.
At 298 K;ΔfH0(SnO2(s))=−581.0 kJ mol−1,ΔfH0(CO2(g))=−394.0 kJ mol−1298 \,K ; \Delta_f H^{0}\left( SnO _{2}(s)\right)=-581.0 \,kJ\, mol ^{-1}, \Delta_{f} H^{0}\left( CO _{2}(g)\right)=-394.0\, kJ \,mol ^{-1},
S0(SnO2(s))=56.0 J K−1mol−1,S0(Sn(s))=52.0 J K−1mol−1S^{0}\left( SnO _{2}(s)\right)=56.0 \,J \,K ^{-1} mol ^{-1}, S^{0}( Sn (s))=52.0 \,J \,K ^{-1} mol ^{-1},
S0(C(s))=6.0 J K−1mol−1,S0(CO2(g))=210.0 J K−1mol−1S^{0}( C (s))=6.0\, J\, K ^{-1} mol ^{-1}, S^{0}\left( CO _{2}(g)\right)=210.0 \,J \,K ^{-1} mol ^{-1},
Assume that the enthalpies and the entropies are temperature independent
