Which of the following statement(s) regarding adsorption is/are not correct? — Surface Chemistry Chemistry Question

💡 Solution & Explanation

At equilibrium in adsorption, the change in Gibbs free energy (ΔG) is zero. Since ΔG = ΔH - TΔS, setting it to zero gives ΔH = TΔS, not ΔH = ΔS. Thus, statement (c) is mathematically incorrect. Therefore, correct answer is C.
