When 1 mole of Fe₂O₃(s)reacts with H₂(g)to form Fe(s)and H₂O(g)according to the following equation,98.8 kJ of energy are absorbed. Fe₂O₃(s)+ 3 H₂(g)$\to$ 2 Fe(s)+ 3 H₂O(g) (A) (B) Is the reaction endothermic or exothermic,and which of the enthalpy diagrams above Represents this reaction?

Question

Quizplus · Accepted Answer

The fact that 98.8 kJ of energy are absorbed indicates that the reaction is endothermic. The enthalpy diagram in option B shows an overall increase in enthalpy from reactants to products, indicating an endothermic reaction. Therefore, option B is the correct choice.
