Question

What are adsorption isobars? Draw the adsorption isobars for the physisorption & chemisorption phenomenon

Answer 1

Answer:

1. A graph drawn between the amount of the gas adsorbed per gram of the adsorbent (x/m) and. temperature 't' at a constant equilibrium pressure of adsorbate gas is known as adsorption isoba
2. With the increase in temperature at constant pressure the extent of adsorption (x/m) will decrease. The graph between extent of adsorption and temperature at constant pressure is called adsorption isobar. In case of chemisorption, the adsorption initially increases with rise in temperature and then decreases.
