Question

Explain two aspects of choosing heterogeneous catalyst.

Answer 1

1. Activity: The catalyst’s ability to accelerate the chemical reaction significantly, sometimes increasing rates by as much as 10¹⁰ times. High activity ensures efficient and fast reaction rates.
2. Selectivity: The catalyst’s ability to direct the reaction to produce a specific product, avoiding unwanted side products. This ensures higher yield and purity of the desired product.
