Question

The molar volume (cm3/mol) of a binary liquid mixture at a (40) specific T and P is given by: V = 200x1 + 300x2 + x1 x2 (20x1 + 10x2) (a) Find expressions for the partial molar volumes of species 1 and species 2 at specific T and P (b) Show that the expressions for partial molar volumes follow the summability relation (c) Show that these expressions satisfy the Gibbs/Duhem equation at constant T and P (d) Find the values for the followings – ̅∞ ̅∞ ?;?;?;?

ONLY part d

v1, v2, v1 bar infinity and v2 bar infinity

Answer 1

Sel V = 2ook + 300 ks + koks (don floxo) V=Joox +30o-300x + (4-2) (gox tlo-lon) V= D 300- looni + (x-xi) ( 10 +104) V = 300 - 100xi + (loxi tlow-loxi-love) V = 300 - looxition-loxis V 300-900-lox Vi = V+re du ana Jo = v-ridy du dv dri :90-300 3 Vi = 300-90x-lox +(1:14)1-90-30xi ) -300-90x-loup -90-3oxia90143ons 210-3041+ you Vy - 300-90x1-1001? 7904+ soni T = 300 -lon²+30x² I=300+ Joup

using given data and required formulae for partial molar properties we can find the pure molar volume and molar volume at infinite dilution
