Total heat evolved by the reaction j

WebThe answer is that relates to the number of moles of the substance as indicated by its coefficient in the balanced chemical reaction. Thus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol.
