WebEnthalpy changes are always measured in kJ, so we need to divide by 1000: 5.016 kJ. Enthalpy change of reaction is -200 kJ mol -1. Note: The negative sign shows that the reaction was exothermic. If the last stage of the calculation (dividing 5.016 by 0.025) worries you, replace the 0.025 by a simpler number like 2.
