Catalysis — Predicted 2026

AI-Predicted Question Angles for UPSC 2026

Based on trend analysis, current affairs, and recurring themes in Catalysis.

Application of catalyst characteristics (activity, selectivity, promoters, poisons) in a novel reaction scenario.

medium

NEET is increasingly moving towards application-based questions. Instead of simply asking 'What is a promoter?', a question might describe a hypothetical reaction and ask what substance would be added to improve yield or direct product formation, requiring students to apply their knowledge of promoters/poisons or selectivity. This tests deeper understanding beyond rote memorization of standard examples.

Comparative analysis of different types of catalysis (homogeneous vs. heterogeneous) based on reaction conditions or separation challenges.

high

Students often memorize examples but might not fully grasp the practical implications of phase differences. A question could present two reaction setups and ask which type of catalysis is more suitable or why, considering factors like ease of catalyst separation or mixing efficiency. This tests analytical skills and a deeper understanding of the practical aspects of catalysis.

Conceptual question on the energy profile diagram, specifically how a catalyst alters the pathway and activation energy without affecting overall energy change.

high

The energy profile diagram is a fundamental visual representation of how catalysts work. Questions often involve interpreting such diagrams or identifying the correct diagram for a catalyzed vs. uncatalyzed reaction. This angle tests the core conceptual understanding of activation energy and thermodynamics in catalysis, which is a perennial favorite for NEET.

Role of active sites and chemisorption in heterogeneous catalysis, potentially linking to surface area or pore structure (e.g., zeolites).

medium

While basic adsorption theory is covered, questions might delve slightly deeper into the nature of active sites, the importance of chemisorption strength, or the concept of shape-selective catalysis (zeolites). This connects catalysis more directly to the 'Surface Chemistry' chapter's broader themes of adsorption and solid surfaces.
