Calculate enthalpy change (in Kj) when 2 mole of liquid acetic acid undergoes dissociation into `CH_(4)(g)` and `CO_(2)(g)` from the following date :
`DeltaH_(vap)[CH_(3)COOH](l)=50kJ//"mole"`
Resonance energy of `DeltaH_(vap)[CH_(3)COOH](g)=-50kJ//"mole"`
Resonance energy `(kJ//"mole"):C-H=400,C-O=350,o=o=500`
