Use the reaction and bond information to answer the question.
H2 + CO2 ---> CH2O2
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=O is 745 kJ / mol, C-O is 358 kJ / mol, O-H is 467 kJ / mol
Is the system endothermic or exothermic and why?
(1 point)
Responses
It is endothermic because more energy is given off by the products versus the amount needed to break up the reactants.
It is endothermic 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 given off by the products versus the amount needed to break up the reactants.
