Consider steady-state diffusion in a binary A–B liquid at constant temperature and pressure. The mole-fraction of A at two different locations is 0.8 and 0.1. Let NA1 be the diffusive flux of A calculated assuming B to be non-diffusing, and NA2 be the diffusive flux of A calculated assuming equimolar counter-diffusion. The quantity
((NA1 – NA2) / NA1) × 100 is __________ (rounded off to one decimal place).
Correct : 53.3
