Frequently asked questions

What makes a Equilibrium question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Equilibrium are high-weightage?

Key areas include Meaning of equilibrium, the concept of dynamic equilibrium, Equilibria involving physical processes: Solid-liquid, liquid-gas, gas-gas and solid-gas equilibria, Henry's law, General characteristics of equilibrium involving physical processes, Equilibrium involving chemical processes: Law of chemical equilibrium, equilibrium constants (Kp and Kc) and their significance, the significance of Delta G and Delta G° in chemical equilibrium, Factors affecting equilibrium: concentration, pressure, temperature, the effect of catalyst, Le Chatelier's principle, and more. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.

Can I practise only important questions on Goodmarks?
