WebChoose your end point as the corner which only has arrows arriving. Now do the calculation: Hess's Law says that the enthalpy changes on the two routes are the same. That means that: ΔH - 3267 = 6 (-394) + 3 (-286) Rearranging and solving: ΔH = 3267 + 6 (-394) + 3 (-286) ΔH = +45 kJ mol -1 stanley cook set for 2WebCalculate the enthalpy change for the reaction: NH4NO3+1/2C= N2+2H2O+1/2CO2 given that the enthalpy of formation of NH4NO3 is -365 KJ/mol , enthalpy of formation of H2O is 242 KJ/mol and enthalpy of formation of CO2 is -394 KJ/mol .
