Question 1
Calculate the mass transfer rate across an air-water interface if the concentration gradient is given as a function of x. Use provided coefficients based on known variables.
💡 Hint: Identify the relevant equations and substitute known values carefully.
Question 2
Propose a method to experimentally determine the mass transfer coefficient in a system where the interface cannot be directly measured.
💡 Hint: Consider using non-invasive methods to gather required data.
