Chemical Kinetics Review Chemical kinetics studies the rate or speed of conversion of reactants into products, the factors that affect the speed of chemical reactions and is also capable of describing how reactions occur. In this review class we will see how to calculate the speed the average speed of consumption or formation of reactants and products, respectively; average speed of chemical reaction, in addition to the factors that affect the speed of reaction and the law of speed, also known as kinetic law, law of mass action and Gulberg-Waage law. 0:00 Introduction 0:10 Chemical Kinetics 2:52 Average Rate of Consumption or Formation 7:26 Average Rate of Reaction 12:11 Observations 14:21 Factors that Affect the Rate of Reaction 17:28 Catalyst 21:10 Rate Law 22:21 Elementary Reactions 26:15 Table of Experiments Exercises Solved in this Class 01:29 (UFPR 2017) A certain chemical species A, when in solution, reacts rapidly with dissolved molecular oxygen and is degraded by it. The rate of this reaction follows the rate law v = k[A]. The graph that adequately represents the relationship between the concentration of species A in solution and the course of the reaction is: 03:51 (UNISINOS) The complete combustion of pentane is represented, qualitatively, by the following equation: C5H12 (g) + O2 → CO2 (g) + H2O (g) Based on the adjusted chemical equation and establishing a consumption of 1.5 mol of pentane in 30 minutes of reaction, it can be concluded that the reaction rate, in moles of carbon dioxide per minute, is: a. 0.05. b. 0.15. c. 0.25. d. 0.30. e. 7.5. 18:24 (ENEM 2010) Some factors can alter the speed of chemical reactions. Three examples in the context of food preparation and preservation are highlighted below: 1. Most food products keep much longer when refrigerated. This procedure reduces the speed of reactions that contribute to the degradation of certain foods. 2. A very common procedure used in cooking is cutting food to speed up its cooking, if you do not have a pressure cooker. 3. When preparing yogurt, enzyme-producing bacteria are added to the milk that speed up reactions involving sugars and milk proteins. Based on the text, what are the factors that influence the speed of chemical transformations related to a. Temperature, contact surface and concentration. b. Concentration, contact surface and catalysts. c. Temperature, contact surface and catalysts. d. Contact surface, temperature and concentration. e. Temperature, concentration and catalysts. (Unesp) Carbonyl chloride gas, COCl2 (phosgene), extremely toxic, is used in the synthesis of many organic compounds. Knowing the following data collected at a given temperature: ????
