Interpretation Introduction To calculate: Δ H rxn for the given hydrogenation reaction. H 2 C = C H 2 ( g ) + H 2 ( g ) → H 3 C − − C H 3 ( g ) | Explanation For the reaction, H 2 C = C H 2 ( g ) + H 2 ( g ) → H 3 C − − C H 3 ( g ) | Here, we need to break one C = C bond, one H – H bond in the reactant, and we need to form two new C – H bonds and one C – C bond. Thus, Δ H rxn = ∑ Δ H reactants ( bonds broken ) + ∑ Δ H rproducts ( bonds formed ) = ∑ Δ H ( C=C ) + Δ H ( H-H ) + ∑ [ 2 × Δ H ( C-H ) ] + Δ H ( C-C ) Now, we have Δ H − H = 4 3 6
