Title Chemistry. Unit 12, Kinetics and nuclear chemistry : the need for speed / [produced by the Science Media Group at the Harvard-Smithsonian Center for Astrophysics]
Published District of Columbia : Annenberg Learner, 2014


Description 1 online resource (29 min.)
Summary From an instantaneous explosion to the slow rusting of iron, the rates at which different chemical reactions proceed can vary tremendously depending on several factors, including temperature and concentration. Sometimes, like with the rotting of food, chemists want to slow down reaction rates. But often, the goal is to speed them up--and one way to do this is to use a catalyst. In this video, we will learn about catalysts and how using them can lead to cheaper, more effective, and more sustainable drug production processes. We will also discover how the rates of some reactions, like nuclear decay, are unchangeable, and how scientists take advantage of this, using PET scans to reveal the presence of disease
