Explain the two-film resistance theory 10.Why overall mass transfer coefficient is considered in many practical mass transfer operations? 11. Give an example where total resistance equals the liquid film resistance during interphase mass transfer. 12.Derive the relationship between the overall mass transfer coefficient and m individual mass transfer coefficients as-=-+-. Assume the 1 K, k, , equilibrium-distribution represent a straight line. The notations imply their usual meanings. 13.The absorption of a very soluble gas is said to be gas-phase controlling mass transfer and the absorption of a gas of low solubility is said to be liquid-phase controlling mass transfer- Explain.
