Which of the following statements is/are correct regarding the basic terminology and phenomena of su — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Option A is incorrect because the substance on whose surface adsorption occurs is the adsorbent, not the adsorbate. B is the standard definition of sorption. C is correct as heating increases kinetic energy (overcoming adsorption forces) and reducing pressure shifts gas-solid equilibria backward. D is correct as surface area phenomena usually consider the interface up to a $\sim 100\text{ nm}$ depth.
