Identify the reaction which does not liberate hydrogen

Show answer and solution
Lithium hydride reacts
with
Utotal =12nRT+52NRT−52NRTU_{total\ } = \frac{1}{2}nRT + \frac{5}{2}NRT - \frac{5}{2}NRT
=12nRT= \frac{1}{2}nRT
and the reaction is expressed as follows,

a=a0e−bcma = a_{0}e^{\frac{- bc}{m}}
The above reaction proves that the liberation of hydrogen gas is not

possible.
