Balanced thermochemical equation and enthalpy diagram
The decomposition of zinc carbonate, ZnCO3(s), into zinc oxide, ZnO(s), and CO2(g) at a constant pressure requires the addition of 71.5kJ of heat per mole of ZnCO3.
Write a balanced thermochemical equation for the reaction and draw an enthalpy diagram for the reaction, showing the activation energy, Ea, and the enthalpy change for this reaction.
