Description

This lecture covers the influence of temperature on reaction rates, focusing on the Arrhenius equation proposed in 1889 by Svante Arrhenius. It explains how the speed constant 'k' varies significantly with temperature, introducing concepts such as frequency factor, activation energy, and the ideal gas constant. The lecture also delves into the interpretation of activation energy, the collision complex, and the Arrhenius law for elementary reactions. Additionally, it discusses reaction mechanisms, intermediates, and multi-step reactions, emphasizing the role of catalysts in accelerating reactions and lowering activation energy barriers.
