Lecture
This lecture covers reaction mechanisms, including elementary reactions, rate laws, and chain reactions. It explains the concepts of molecularity, catalysis, and catalytic converters. The instructor discusses examples such as hydrogenation and enzyme catalysis, emphasizing the lock-and-key model. The lecture also delves into galvanic cells, standard potentials, and electromotive force in batteries, providing insights into redox reactions and free energy. Key topics include the Daniell cell, salt bridges, and the measurement of standard potentials. The session concludes with discussions on equilibrium constants, calorimetry, and spontaneous changes in redox reactions.
