Question

For Russell method, ln Kbj is defined as

(a) Aj – (Bj/Tj)

(b) – (Bj/Tj)

(c) Aj (Bj/Tj)

(d) Aj + (Bj/Tj)

The question was asked in class test.

The above asked question is from Inside Out Method in portion Rigorous Distillation Calculations of Distillation Design

Answer 1

Right choice is (a) Aj – (Bj/Tj)

For explanation I would say: For Russell method ln Kbj = Aj–(Bj/Tj), the Russell equations resembles the same as that of the Antoine equation for detecting vapor pressure.
