Calculate the strength of H-bond between F^(-)(g) and CH_(3)COOH (g) from the given data. {:(DeltaH_("solution")[KF. CH_(3)COOH(s)]" in glacial acetic acid",=,-3" kJ/mole"),(DeltaH_("solution") [KF(s)]" in glacial acetic acid",=,+35" kJ/mole"),("Lattice Enthalpy KF(s)",=,+797" kJ/mole"),("Lattice enthalpy of " KF. CH_(3)COOH(s),=,+734" kJ/mole"),(DeltaH_("vaporization") [CH_(3)COOH (l)],=,+21" kJ/mole"):}

Answer»

SOLUTION :
`-3=+734+E_(H)-797+35-21`
`E_(H)=-3-734-35+797+21=+46" kJ/mole"`
