Which of the plots is adsorption isobar for chemisorption?

Correct answer

Step-by-step solution

chemisorption involves a high activation energy. so, it first increases and then decreases with increase in temperature. The initial increase is due to the heat supplied which act as activation energy required in chemisorption but later it decreases due to exothermic nature of adsorption at equilibrium.
