Challenge Problems
Push your limits with advanced challenges
If a system has a liquid phase resistance of 1500 and a gas phase resistance of 300, calculate the total resistance and identify which phase controls the mass transfer.
💡 Hint: Identify the controlling phase based on resistance values.
A gas has a concentration of 0.05 mol/L, and the liquid phase has 2 mol/L. If the Henry’s constant is 40 L/mol, what will be the equilibrium concentration in the gas phase?
💡 Hint: Apply the formula learned from Henry's law.
