Question

when producing hydrogen iodide, the energy of the reactants is 581 kj/mol, and the energy of the products is 590 kj/mol. the equation is shown. h₂ + i₂ → 2hi what is the total energy of the reaction? is this an endothermic or exothermic reaction? (1 point) 9 kj/mol, exothermic -9 kj/mol, endothermic 9 kj/mol, endothermic -9 kj/mol, exothermic

Explanation:

Step1: Calculate energy change

$\Delta H=E_{products}-E_{reactants}=590 - 581=9$ kJ/mol

Step2: Determine reaction type

Since $\Delta H> 0$, heat is absorbed and it is endothermic.

Answer:

9 kJ/mol, endothermic
