Calculate the magnitude of standard free...

Calculate the magnitude of standard free energy of formation of ammonium chloride at `25^(@)C` (approximate integer in Kcal`mol^(-1)`), the equation showing the formation of `NH_(4)CI` from its elements is
`1/2NH_(4)(g) + 2H_(2)(g) + 1/2CI_(2)(g) rarr NH_(4)CI(s)`
For `NH_(4)CI, DeltaH_(f)^(@)` is `-313 KJ mol^(01)`, Also given that
`" "S_(N_(2))^(@) = 191.5 JK^(-1) mol^(-1)" "S_(N_(2))^(@) = 130.6 JK^(-1) mol^(-1)`
`" "S_(CI_(2))^(@) = 223.0 JK^(-1) mol^(-1) " "S_(NH_(4)CI)^(@) = 94.6 JK^(-1)mol^(-1)`
