1 mole of Fe3O4 reacts with H2 to form Fe and H2O. 151 kJ of energy are absorbed. What is the value of q in kJ? Also, Is this a exo or endothermic reaction?

Heat is absorbed by the system, so it is endothermic.
Fe3O4 +4H2 ===> 3Fe + 4H2O
∆H = 151 kJ
Fe3O4 +4H2 ===> 3Fe + 4H2O
∆H = 151 kJ

what is q?
