Formation enthalpy from data
In a school extension laboratory, the sum of product formation enthalpies is \(-384\,\text{kJ mol}^{-1}\) and the sum of reactant formation enthalpies is \(-140\,\text{kJ mol}^{-1}\). Calculate \(\Delta H_{\text{rxn}}\). Enter the answer and choose the interpretation that matches the HL chemistry evidence.
