Some of the hardest topics on a college chemistry midterm include stoichiometry and balancing complex chemical equations. Thermodynamics, especially Gibbs free energy and entropy, can also be very challenging. Students often struggle with equilibrium concepts and applying Le Châtelier’s principle to different scenarios. Kinetics, reaction mechanisms, and rate laws require both math and conceptual understanding. Acid–base equilibria and buffer solutions are also tricky because they combine formulas with reasoning. Many students even think, “I wish someone could do my proctored chemistry exam for me” when overwhelmed. With practice and review, though, these tough topics become much more manageable. https://domyexamforme.us.com/take-my-che...
