The equation for the reaction between gaseous hydrogen and gaseous iodine to form gaseous hydrogen iodide is shown.
H 2 (g) + I 2 (g) → 2HI(g)
The reaction is exothermic. Which statement explains why the reaction is exothermic?

Question

The equation for the reaction between gaseous hydrogen and gaseous iodine to form gaseous hydrogen iodide is shown.  
 H 2 (g) + I 2 (g) → 2HI(g)   
 The reaction is exothermic. Which statement explains why the reaction is exothermic?

Answer

More energy is released when two HI bonds are formed than is used when the H–H and     I–I bonds are broken.

Answer

Energy is released when H–H and I–I bonds are broken.

Answer

The bond energies of the reactants are larger than the bond energies of the products.

Answer

The products are at a higher energy level than the reactants.
