Calculate the standard enthalpy of formation of gaseous diborane, B2H6,
using the following thermochemical information: (Hints: (i) Standard
states of B2O3 and B are solid, (ii) Look carefully at equations 1 and 2
and what they describe)
2B2O3(s) H1 = -2509.1 kJ
Equa. 2. 2H2(g) + O2(g) (2H2O(l)
H2 = -571.7 kJ
Equa. 3 B2H6(g) + 3O2(g) (B2O3(s) + 3H2O(l)
H3 = -2147.5kJ
