This program explores the direction of chemical reactions by seeking completion of both endothermic and exothermic reactions. Illustrated examples lead to a comparison of steady state and closed systems and to an apparently stopped reaction—equilibrium. (10 minutes)

		Dynamic Equilibrium By focusing on the behavior of hydrogen iodide, this program describes how all chemical reactions operate in two directions. It uses a collision model, based on the kinetic molecular theory, to explain how molecules behave to produce dynamic equilibr...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Reaction Tendencies This program introduces Le Chatelier's principle: if a system in equilibrium is subject to stress, the system tends to react in such a way as to oppose the effect of the stress. It examines this principle by observing the effects of two types of stre...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		The Equilibrium Constant A dance analogy is applied to the hydrogen iodide system to illustrate how shifts in equilibrium occur. The program restates that qualitative predictions are not enough, and then examines how chemists are able to ascertain the equilibrium constant by...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		Reaction Kinetics This program provides an examination of why some chemical reactions happen more quickly than others. A chain mechanism model shows how energy released by reacting molecules influences other molecules, and leads to a clearer understanding of exothermi...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
		The Haber Process This program provides a study of the development of the process invented by Fritz Haber for producing ammonia from atmospheric nitrogen, with a review of the concepts presented in the first five programs. The program recounts the major events of Habe...(more details)		VHS $49.95 DVD $49.95 DVD + 3-Year Streaming $74.93 3-Year Streaming $49.95
