Step-by-step solution
Freundlich adsorption isotherm, an adsorption isotherm is a graph that represents the variation in the amount of adsorbate (x) adsorbed on the surface of the adsorbent with the change in pressure at a constant temperature. As the temperature increases, adsorption decreases. Therefore, the correct relation is given in option (3).
