Interpretation Introduction To Calculate: Δ H rxn for the reaction: C ( s ) + 2 H 2 O ( g ) → 2 H 2 ( g ) + C O 2 ( g ) . Explanation For the reaction: C ( s ) + 2 H 2 O ( g ) → 2 H 2 ( g ) + C O 2 ( g ) Here, we need to break four O – H bonds in the reactant , H 2 O as in H 2 O , there are two O − H bonds and we need to form two H – H bonds and two C = O bonds. Δ H rxn = ∑ Δ H reactants ( bonds broken ) + ∑ Δ H products ( bonds formed ) = ∑ 4 × Δ H ( O-H ) + ∑ 2 × Δ H ( H-H ) + 2 × Δ H ( C=O ) Now, we have Δ H C = O = 799 k J / m o l
