The enthalpy and entropy change of trimerization of gas phase `(3A(g) to A_(3)(g))` at `300 K` are `-100 K//J "mole"` amd `-400J//K"mole"` respectively . If the bolling points of A and `A_(3)` are 300 K and 400 K respectively . Given : `C_("pm"_(A_3(g)))=C_("pm"_(A_3(l))),d_(A(l))=1.2 g//ml`, `d_(A_(3(l)))`= `1.5 g//ml`, molar masss of A =20 garm Assume : Density of `A_(3)(l)` and `A(l)` are independent of pressure.A. `DeltaH` " for trimerisation in liquid phases " at` 300 K` =-` 125 KJ mol^(-1)`B. `DeltaS` "for trimerisation in liquid phase " at `300 K` =-` 275 kJmol^(-1)`C. At standard state of `300 K DeltaG` of the reaction : `3A(l) to A_(3) (l) "is" 7500 J`D. The equilibrium pressure of the reaction `3(A) to A_(3) (l) is 7.501xx10^(8) "Pa at" 300 K` |
