11: Kinetics and Equilibrium Activated complex: an intermediate state that is formed during the conversion of reactants into products‚ the structure that results at the maximum energy point along the reaction path. Activation energy: a chemical reaction is the difference between the energy of the activated complex and the energy of the reactants. Catalyst: substance that increases the rate of a chemical reaction by reducing the activation energy‚ but which is left unchanged by the reaction.

Chapter 1 Chemical Reactions and Equations Q.1. Why should magnesium ribbon be cleaned before burning in air ? Ans: Magnesium ribbon is a very reactive metal. When stored it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide being a stable compound prevents further reaction of magnesium with oxygen. The magnesium is cleaned before burning in air to remove this layer so that the metal can be exposed to air properly. Q.2. Write the balanced

Experiment N | Kinetics of the Depolymerization of Diacetone Alcohol via Basic Catalysis | | Ingrid Tafur -5672578 | 2/11/2011 | CHM233O Partner: Laura Marrongelli Demonstrator: Cheryl McDowall Objective The rate constant of the depolymerization of diacetone alcohol via basic catalysis was determined by monitoring the change in volume as a function of time at constant temperature of a pseudo first order reaction where the species in excess was sodium hydroxide. This was accomplished

During an undercover investigation‚ Officer Cline witnessed Defendant #1 purchase a bag of what appeared to be marijuana and LSD. When Officer Cline approached the dealer (Defendant #2)‚ he was given a similar bag. Following the purchase‚ officers approached and arrested both defendants on narcotics violations. Forensic tests later revealed that the contents of the bag were nothing more than honey and dried leaf matter and rolling paper coated with lime extract. The defense attorneys for both defendants

Discussion The reaction through which 4-mrthaoxyacetophenone is converted to 4-methoxybenzoic acid is a haloform reaction. This reaction involves two distinct stages that occur in the same environment. The first stage occurs through the based-catalyzed halogenation of the ketone that forms a trihalo ketone. First‚ the bleach is transformed into chlorine and hydroxide ions through the following reaction: Then‚ the hydroxyl is able to attack the rather acidic (pKa ~ 20) α-hydrogen of the ketone

<i>1. State the five assumptions of the Kinetic-Molecular Theory of gases.</i><br><br>a) Gases consist of large numbers of tiny particles. These particles‚ usually molecules or atoms‚ typically occupy a volume about 1000 times larger than occupied by the same number of particles in the liquid or solid state. Thus molecules of gases are much further apart than those of liquids or solids.<br><br>Most of the volume occupied by a gas is empty space. This accounts for the lower density of gases compared
