Zeolites act as incredibly effective shape-selective catalysts in the petrochemical industry. Which — Surface Chemistry Chemistry Question

💡 Solution & Explanation

Statement A is the chemical definition of a zeolite (aluminosilicate). Statement B is entirely false; their key feature is extreme internal porosity. Statement C explains the mandatory activation step to prepare the zeolite for catalysis. Statement D correctly specifies the characteristic molecular sieve pore size range ($260-740\text{ pm}$) that gives them their shape-selective abilities.
