Work all the parts to get the most points.The standard molar enthalpy of formation of diborane, B₂H₁ (g), cannot be determined directly because the compound cannot be prepared by the reaction of boronand hydrogen. It can be calculated from other enthalpy changes, however. The following enthalpy changes can be measured.4 B(s) + 3 O₂(g) → 2 B₂ O3 (s)A, H = -2543.8 kJ/mol-rxnH₂(g) + 1/2 O₂ (g) → H₂O(g)▲,H° = −241.8 kJ/mol-rxnB2 H6 (g) + 3 O2 (g) → B2 O3 (g) + 3 H₂O(g) A₁H° = −2032.9 kJ/mol-rxn
