Question

hydrogen and iodine gases react to produce hydroiodic acid according to the reaction. h₂ + i₂ → 2hi. how much total bond energy in kj/mol is in the products of the reaction? (1 point) o 448 o 594 o 453 o 297

Explanation:

Step1: Identify bond in product

The product is HI and there are 2 moles of HI in the reaction.

Step2: Know HI bond - energy

The bond - energy of a H - I bond is 297 kJ/mol.

Step3: Calculate total bond - energy of products

Since there are 2 moles of HI, the total bond energy of products is $2\times297$ kJ/mol.
$2\times297 = 594$ kJ/mol

Answer:

594 kJ/mol (corresponding to option with value 594)
