General Chemistry II Exam Review
Course Introduction
General Chemistry II builds upon foundational concepts introduced in the first semester of general chemistry, delving deeper into topics essential for a comprehensive understanding of chemical reactions and behavior. This course covers thermodynamics, chemical kinetics, equilibrium, acids and bases, electrochemistry, and introduces students to coordination chemistry and nuclear chemistry. Through a combination of lectures, laboratory experiments, and problem-solving sessions, students develop analytical skills to interpret scientific data and apply theoretical knowledge to practical situations. General Chemistry II is fundamental for students pursuing further studies in chemistry, biology, engineering, and health sciences.
