Question 1
What is the relationship between mass transfer coefficients and flux?
- They are directly proportional
- They have no relationship
- They are inversely proportional
💡 Hint: Think about their definitions.
Question 2
Is it true that the overall mass transfer rate is influenced by the phase with the highest resistance?

Challenge Problems
Push your limits with challenges.
Question 1
If k1 = 0.1 and k2 = 0.9, and the interface concentrations are 5 M for liquid and 0.5 M for gas, calculate the flux.
💡 Hint: Ensure you use the correct coefficients for each phase.
Question 2
A polluted river has a concentration of 12 ppm and the air above has 2 ppm. If you find that the gas resistance is negligible, calculate the overall resistance impacting the transfer rate.
💡 Hint: Assess the given data against the relationships discussed.
