When 1 mole of Fe₂O₃(s)reacts with H₂(g)to form Fe(s)and H₂O(g)by the following reaction,98.8 kJ of energy is absorbed. Fe₂O₃(s)+ 3 H₂(g)→ 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 is absorbed indicates that the reaction is endothermic. Therefore, we can eliminate choices C and D. Looking at the enthalpy diagrams, we can see that diagram B shows an endothermic reaction as it has a positive delta H value for the reaction. Therefore, the correct choice is B.
