Gas- Liquid and Gas –Liquid –Solid Reactions

1. A stagnant layer exists in both the gas and the liquid phases. 2. The stagnant layers or films have negligible capacitance and hence a local steady-state exists. 3. Concentration gradients in the film are one-dimensional. 4. Local equilibrium exists between the the gas and liquid phases as the gas-liquid interface 5.
