Given enthalpy of formation of CO_2(g) and CaO(s) are -94.0 kJ and -152 kJ respectively and the enthalpy of the reaction, CaCO_3(s)rarrCaS(s)+CO_2(g) is 42 kJ. The enthalpy of formation of CaCO_3(s) is

For the reaction, CaCO_(3)(s)toCaO(s)+CO_(2)(g),DeltaH^(0)=+179.1kJ*mol^(-1) and DeltaS^(0)=160.2J*K^(-1) . If DeltaH^(0) and DeltaS^(0) are temperature independent, then temperature above which the reaction will be spontaneous is equal to-
