Iron enthalpy of formation
WebThe enthalpy change for this reaction is −5960 kJ, and the thermochemical equation is: C12H22O11 + 8KClO3 12CO2 + 11H2O + 8KCl ΔH = −5960kJ Check Your Learning When … WebSep 10, 2024 · Explanation: The Standard Heat of Formation ( ΔH o f) is given in terms of Kj per 1 mole. By definition ΔH o f is the heat liberated or gained on formation of one mole of substance from basic elements in their standard states. The Standard Enthalpy of Formation for elements in their basic standard states is equal to 'zero' Kj/mole.
