(a) The standard molar enthalpy of formation, Delta Hf_0, for diborane, B2H6 (g), cannot be directly cause the compound cannot be prepared by the reaction of boron and hydrogen. It can be calculated, however, using the following reactions: 4B(s) + 3O2(g) 2 rightarrow B2O3(s) Delta H degree_rxn = - 2543.8 kJ 2H2(g) + O2(g) rightarrow 2H2O(g) Delta H degree_rxn Delta H degree _rxn = -484. kJ B2H6(g) + 3 O2(g) rightarrow B2O3(s) + 3H2O(g) Delta H degree_rxn = -2032.9 kJ Calculate Delta H degree f for B2H6(g).
