Identify the strictly true statement(s) regarding the effect of temperature on different types of ad — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Statement A is correct; physisorption involves no activation energy and is strictly exothermic. Statement B is correct; chemisorption behaves like a chemical reaction requiring an initial activation energy barrier to be overcome. Statement C is correct; an increase in temperature can supply the necessary activation energy to convert van der Waals interactions into chemical bonds (e.g., $N_2$ on Iron). Statement D is incorrect; the isobar is bell-shaped, not horizontal.
