question_answer 63)

    Freundlich adsorption isotherm is given by the expression  Which of the following conclusions can be drawn from this expression? (a) When = 0, the adsorption is independent of pressure (b) When  = 0, the adsorption is directly proportional to pressure (c) When vs p graph is a line parallel to x - axis (d) When n = 0, plot ofvs p is a curve

Answer:

                    (a, c) According to Freundlich adsorption isotherm At = 0 this equation becomes Extent of adsorption is independent of pressure. (c)                    Hence,  vs p graph can be plotted as
