The empirical Freundlich adsorption isotherm for gases is represented by the equation . Which of the — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Statement A is a true characteristic of the empirical model. Statement B is false; at very high pressures, the extent of adsorption becomes independent of pressure (saturation), meaning $1/n$ mathematically approaches 0, not 1. Statement C describes the correct linear transformation for verification. Statement D is correct; because it is an empirical power-law, it incorrectly implies adsorption will keep increasing indefinitely, failing to model the saturation plateau.
