soal dan jawaban dasar-dasar pemisahan analitik (DDPA)

Hitunglah tekanan n-heksana pada 500 torr dan 100 torr ?

Jawab :

Dik: -∆HV =-6400

R = 1,987 kal/mol°

T = 273 K

T1 = 333

Dit : P n-heksana pada 500 torr ?

Peny:

Log p2/p1           = -∆HV/2,303.R(1/T2-1/T1)

Log 500/565 = -6400/2.303.1,987 (1/T2-1/333)

Log 0,88495 = -6400/4,57606 (1/T2-1/333)

-0,,05307             = -1398,58306 (1/T2-1/333)

            = -1398,58306/T2 + -1398,58306/333

-0,,05307             = -1398,58306/T2 + 4,19995

-0,,05307 - 4,19995 = -1398,58306/T2

-4,25302 = -1398,58306/T2

T2 = -1398,58306/-4,25302

        = 328,84469

T2 = 328,84469 - 273

T2 = 55,80°C
