Which consequence results when zeolites catalyze reactions at increased temperatures?

A)Reduced active site surface area
B)Enhanced product selectivity is observed
C)Diffusion limitations increase sharply
D)Intraparticle concentration becomes uniform

💡 Explanation

When temperatures increase, *diffusion limitations* become prominent because high temperatures escalate the kinetic energy of reacting molecules. Therefore, molecules move faster, and pore diffusion constraints impact reactions greater, rather than increasing selectivity.
