Experiments were conducted to determine the flux of a species A in a stagnant medium across a gas-liquid interface. The overall mass transfer co-efficient based on the liquid side for dilute systems for the above was estimated to be 4 x 10 -3 kg mole/m 2 .s. The equilibrium data for the system is given as y = 2x. The flux across the interface (in kg mole/m 2 .s) for bulk concentrations of A in gas phase and liquid phase as y = 0.4 and x = 0.01 respectively is Options: A . &nbsp5.6 x 10-4 B . &nbsp8.5 x 10-4 C . &nbsp5.6 x 10-3 D . &nbsp8.5 x 10-3

Question

Experiments were conducted to determine the flux of a species A
in a stagnant medium across a gas-liquid interface. The overall mass
transfer co-efficient based on the liquid side for dilute systems for
the above was estimated to be 4 x 10^-3 kg mole/m².s. The equilibrium data for the system is given as y = 2x. The flux across the interface (in kg mole/m² .s) for bulk concentrations of A in gas phase and liquid phase as y = 0.4 and x = 0.01 respectively is

Options:

A . 5.6 x 10-4

B . 8.5 x 10-4

C . 5.6 x 10-3
