- Is this question formulated correctly? If not, please fix it and return the output as a JSON of the form: {'question': 'question text'}. Here is the question: Calculate ΔH° for the reaction H2(g) + Br2(g) → 2 HBr(g) using bond energy values. The ΔH°f of HBr(g) is not equal to one-half of the value calculated. Account for the difference.
