Benzene and toluene have equal mole fractions in their mutual solution. What do you expect about their mole fraction n the vapour phase at the same temperature? Explain. (Given : p_("Benzene")^(@)=3xxp_("Toluene")^(@)) |

Answer» <P> Solution :`p_(B)//p_(T)=p_(B)^(@)//p_(T)^(@)(because x_(B)=x_(T)).` But `p_(B)^(@)//p_(T)^(@)=3` (GIVEN). Hence, `p_(B)//p_(T)=3.` But `p_(B)//p_(T)=3` implies that `y_(B)//y_(T))=3` in the VAPOUR phase because vapour pressure in the vapour phase are in the ratio of their no. of moles of mole fractions. |
