Application of phase rule to three component system

phase rule and there application

1. Application of phase rule to three component system Guided by Presented by Dr.Laxmi T antuvay Gayatri M uchhala

2. Phase rule is discovered by Willard Gibbs between 1875 and 1876 Definition:- The some of the number of degrees of freedom plus number of phases of a heterogeneous system at aquarium is equal to the number of components present in the system plus two is called phase rule . F + P = C + 2 F = C – P + 2 PHASE RULE

3. PHASE COMPENT DEGREE OF FREEDOM CONTAINT

4. any homogeneous distinct part of a system which is mechanically separable and bounded by a definite surface example:-ice (s)= H2O water(l)=H2O Vapour(g)=H2O phases

5. The smallest number of independently variable constituent by means of which the composition of each can be represent by means of a chemical equation Ex.. In water vapour and ice system .there is only one component present in this because H and O can not varied independently so it is a one component system Component

6. The number of variable factor such as temperature pressure or concentration which must be arbitraly fixed in order to define the system completely Example:-a gases mixture of two gases C02 and N2 in equilibrium to defined this system three variable viz, composition (35%co and 65% N2)temp. 40degree and pressure 760mm are required to be arbitrarily fixed hence the system has three degree of freedom Degree of freedom

7. One component system Two component system Three component system There are three types of component

8. Phase rule for one component system F=C-P+2 F=1-P+2 F= 3- P Here maximum degree of freedom can be only 2 One component system

9. Phase rule when apply in two component system F=C-P+2 F=2-P+2 F= 4 – P Here maximum degree of freedom is three Two component system

10. phase rule for three component system According to phase rule ,the degree of freedom in a three component system in three component system is given by, F=c-p+2 F=3-p+2 F = 5+ P point at which all the phases are stable together is known as quintuple point

11. The variation in concentration of the three component mixture is expressed by means of triangular diagram The representation of compositions in a three-component Presentation of ternary system

12. A represents 100 percent of component B, 100 percent of component B, C 100 percent of component C; Q represents 65 percent of B, 35 percent of C; R represents 50 percent of A, 30 percent of B, 20 percent of C ;represents 25 percent of A, 20 percent of B, 55 percent of C.

13. Formation of one pair of partially miscible liquids. Formation of two pairs of partially miscible liquid Formation of three pairs of partially miscible liquids Partial miscible three liquid system

14. Formation of one pair of partially miscible liquids

15. CH3COOH completely dissolve in water and chloroform but water and chloroform are partially soluble in each other

16. System of water, phenol ,aniline example

17. Formation of three pairs of partial miscible liquid

18. Succinic nitrile –water ether system
