For the reaction 2A+B→3C2A + B \rightarrow 3C, the standard enthalpies of formation are: ΔHf°(A)=−125 kJ/mol\Delta H_f°(A) = -125\text{ kJ/mol}, ΔHf°(B)=+85 kJ/mol\Delta H_f°(B) = +85\text{ kJ/mol}, ΔHf°(C)=−240 kJ/mol\Delta H_f°(C) = -240\text{ kJ/mol}. Calculate ΔHrxn°\Delta H_{rxn}° using proper stoichiometry and sign conventions.
