Interpretation Introduction To calculate: Δ H o for the reaction H 2 ( g ) + B r 2 ( g ) → 2 H B r ( g ) and compare it with Δ H f o of HBr ( g ) and account for the difference. Explanation The reaction is given by H 2 ( g ) + B r 2 ( g ) → 2 H B r ( g ) . We need to break one H – H bond and one B r – B r bond on the reactant side and form two H – B r bonds on the product side. Δ H rxn = ∑ Δ H reactants ( bonds broken ) + ∑ Δ H rproducts ( bonds formed ) = ∑ Δ H ( H-H ) + Δ H ( Br-Br ) + ∑ 2 × Δ H ( H-Br ) Hence, we have ∑ Δ H reactants <
