According to Langmuir adsorption isotherm, the amount of gas adosobed at very high pressureA. reachaes a constant limiting valueB. goes on increasing with pressureC. goes on increasing with pressureD. increases first and decrrease later with pressure

Answer» Correct Answer - A
Langmuir adsorption isotherm deals in terms of chemical adsorption which fails at high pressure because the mas adsorbed reaches a constant value when the adsorbed suface is completely covered by a unimolecular layer of gases .
