GATE Chemical Engineering
Topic Guides

GATE Chemical Engineering draws from a fixed set of subjects every year, and the fastest way to study efficiently is to know how they relate to each other rather than treating each as an isolated formula sheet. This page groups all 16 topic guides on ChemeGate into four clusters that mirror how the subjects actually build on one another: Core Transport (the physics of momentum, heat, and mass moving through equipment, the foundation everything else assumes you already have), Separations (the specific unit operations, distillation, absorption, drying, evaporation, that Mass Transfer theory makes possible), Reactions & Control(thermodynamics, reaction engineering, and the process-control math that governs how a plant behaves once it's running), and Applied (economics, industrial technology, and the engineering mathematics that underpins all of the above).

Each guide follows the same structure, syllabus-mapped subtopics, essential formulas with derivations, GATE-style worked practice problems, PYQ frequency by subtopic, a recommended study order, and common mistakes, so once you know the shape of one guide, you know the shape of all sixteen. Mass Transfer additionally works as a hub: its own guide covers the fundamentals, then links out to five deeper guides (Distillation, Absorption & Extraction, Drying & Humidification, Evaporation & Crystallization, and Diffusion Fundamentals) under Separations and Core Transport below.
