Find the bond enthalpy (in kJ/mol) of one "three centre two electron bond" in B_(2)H_(6) {B-H-B rarr 2B(g)+H(g)} from the given data. {:(DeltaH_(f)^(@) [BH_(3)(g)]=100" kJ/mole",,DeltaH_(f)^(@) [B_(2)H_(6)(g)]=36" kJ/mole"),(DeltaH_("atm")[B(s)]=565" kJ/mole",,DeltaH_("atm")=[H_(2)(g)]=218" kJ/mole"):} |
