General Chemistry MCAT Practice

General Chemistry makes up a meaningful share of the Chemical and Physical Foundations section, testing atomic structure, bonding, stoichiometry, gases, thermodynamics, kinetics, and equilibrium. Strong performance here depends less on memorization and more on comfort manipulating equations under time pressure — Henderson-Hasselbalch, the ideal gas law, and Keq expressions show up constantly, in both standalone questions and passage-based reasoning. Because it underlies biochemistry and physiology questions elsewhere on the exam, gaps here tend to compound.
