Evaluation

This is the textbook's own end-of-chapter evaluation set for the unit, testing the material from the meaning of equilibrium and its physical/chemical classification through the law of mass action, the equilibrium constant and its Kp-Kc relationship, the reaction quotient, and Le Chatelier's principle, up to the Van't Hoff equation. The first part, 'Choose the Best Answer' (numbered 1-25), is multiple choice -- one question is explicitly drawn from a NEET 2017 paper -- and covers conceptual reasoning, matching, and short numerical calculations built around Kc, Kp, Q and Le Chatelier shifts. The second part, 'Write Brief Answer' (numbered 26-51, continuing the book's own numbering), ranges from one-line law/principle statements and short conceptual explanations through to full derivations (the general …
