Question 5.
Calculate the mass flux of benzene evaporating from water given the mass transfer coefficients and concentration gradients.
Show hintHide hint
Start by applying the steady-state equation between both phases.
Question 6.
Propose a design for an experiment to measure diffusion rates at the air-water interface.
Show hintHide hint
Think about setup configurations that promote accurate readings without disturbing the interface.
