Chem107 Exam 2 – 20 Exam Questions and Verified Answers on Reaction Kinetics, Arrhenius Equation, and Acid–Base Chemistry (Chem107)

This document contains approximately 20 exam questions with verified answers designed to help students prepare for Chem107 Exam 2 in a university General Chemistry course. The material focuses on important topics in chemical kinetics and acid–base chemistry, including rate laws, reaction order (zero-order, first-order, and second-order reactions), units of rate constants, half-life expressions, and the interpretation of reaction rate graphs. It also introduces the Arrhenius equation, activation energy calculations, and the use of linear equations such as the slope equation (y = mx + b) for Arrhenius plots used to determine reaction kinetics relationships. These concepts are presented in a concise question-and-answer format that allows students to review definitions, formulas, and problem-solving strategies commonly tested in chemistry exams. The document further explores reaction mechanisms and energy diagrams, including the concept of reaction intermediates, the effect of catalysts on reaction pathways, and how activation energy relates to forward and reverse reactions. It also reviews important acid–base theory concepts such as Arrhenius acids and bases, Brønsted–Lowry acid–base definitions, conjugate acid–base pairs, and the amphoteric nature of water. Additional topics include strong and weak acids, strong bases, pH calculations, the relationship between hydrogen ion concentration and pH, and the formulas used to convert between pH, H⁺ concentration, and OH⁻ concentration. These explanations provide a quick but comprehensive review of fundamental chemistry principles required for solving exam questions in kinetics and acid–base equilibria. The content aligns with the learning objectives typically covered in General Chemistry II courses and complements widely used textbooks such as Chemistry: The Central Science by Theodore L. Brown, H. Eugene LeMay, Bruce E. Bursten, and Catherine Murphy, which include detailed coverage of chemical kinetics, reaction mechanisms, and acid–base chemistry. As shown throughout the document, formulas, definitions, and conceptual explanations are organized for rapid review and exam preparation.
