Is this system endothermic or exothermic, and why? * H2 + CO2 CH202 Reactant bond energies: H-H is 432 kJ/mol, C=O is 799 kJ/mol Product bond energies: C-H is 413 kJ/mol, C=0 is 745 kJ/mol, C-O is 358 kJ/mol, O-H is 467 kJ/mol It is exothermic because more energy is given off by the products versus the amount needed to break up the reactants. It is exothermic because more energy is needed to break up the reactants versus the amount given off by the products. It is endothermic because more energy is needed to break up the reactants versus the amount given off by the products. It is endothermic because more energy is given off by the products versus the amount needed to break up the reactants.
