Question

Show that the total vapour pressure over the two solution of two liquids 1 and 2 at a particular temperature varies linearly with the mole fraction of a component

Answer 1

Answer:

We kmow that,

According to Dalton's Law of Partial Pressures,

partial Pressure of each component gas is proportional to their mole fractions in the vapour.

Hence,

Partial Pressure of A =Pa=400×0.45=180

Partial Pressure of B= Pb=400×(1−0.45)=220

Also, Partial Pressure of the gas in the vapour

= (Vapour Pressure) × (Mole Fraction of Liquid in solution)

Hence,

Vapour Pressure of A =Va=1800.65≈277

Vb=

(1−0.65)

220

≈629

Answer 2

Explanation:

In heterolytic cleavage, a covalent bond breaks in such a way that one fragment gets both of the shared electrons. In homolytic cleavage, a covalent bond breaks in such a way that each fragment gets one of the shared electrons. The word heterolytic comes from the Greek heteros, "different", and lysis, "loosening".
