Answer 1

To determine the total bond energy in the products of the reaction H₂ + I₂ → 2HI, we need to consider the bond energy of the bonds formed in the products.

In the reaction, 2 molecules of HI are formed. The bond energy for the H-I bond is 297 kJ/mol. Since there are 2 HI molecules formed, we need to calculate the total bond energy for the products:

Total bond energy in products = 2 × (Bond energy of H-I) Total bond energy in products = 2 × 297 kJ/mol Total bond energy in products = 594 kJ/mol

Therefore, the total bond energy in the products of the reaction is 594 kJ/mol.
