The kinetic theory of gases describes a gas as a large number of small particles (atoms or molecules)‚ all of which are in constant‚ random motion. The rapidly moving particles constantly collide with each other and with the walls of the container. Kinetic theory explains macroscopic properties of gases‚ such as pressure‚ temperature‚ or volume‚ by considering their molecular composition and motion. Essentially‚ the theory posits that pressure is due not to static repulsion between molecules‚ as

Introduction The purpose of this lab is to determine: the coefficient of friction between a rubber stopper and a wooden ramp the coefficient of static friction between a wooden block and a wooden ramp the coefficient of kinetic friction between a wooden block and a wooden ramp The design of this experiment was done by placing a rubber stopper / wooden block onto a wooden ramp and tilting the ramp at a certain degree to cause the stopper / block to move. The measurements of the vertical distance

Enzymes are naturally occurring biological catalysts that are extremely efficient and specific. Enzymes accelerate the rate of a reaction by factors of at least a million as compared to the same reaction without the enzyme. Most biological reaction rates are not perceivable in the absence of the enzyme. The term enzyme was first used by a German pshysiologist Wilhelm Kühne in 1897. There are over 700 different kinds of enzymes that have been identified. Enzymes can be classified into several categories

Kinetics of the Decomposition of Hydrogen Peroxide Lab Introduction: In this week’s lab experiment‚ the rate of decomposition of hydrogen peroxide forming oxygen gas will be observed and studied. Since the rate of a chemical reaction is dependent on two things; the concentrations of the reactants and the temperature at which the process is performed‚ the rate can be measured at which a reactant disappears or at which a product appears. When measuring the rate‚ the rate law will be applied. The

Institute of Chemistry‚ University of the Philippines‚ Diliman‚ Quezon City 1101 Philippines ABSTRACT The rationale of the experiment is basically founded in the concept of reaction rates as affected by enzyme‚ and how the enzyme works is competed by a competitive inhibitor‚ thereby impeding the forward reaction. In this experiment‚ o-diphenol oxidase‚ an enzyme that causes the browning in fruits‚ was extracted from banana and reaction rate of this was established

Use the knowledge of kinetics to explain each of the following statements. a. An increase in temperature at which a reaction takes place causes an increase in reaction rate . An increase in temperature means increasing the energy of the molecules present. If the molecules has more energy ‚ then more of the them will collide often with enough energy ‚ to overcome the activation energy barrier. causing the reaction to proceed more quickly. b.An addition of the catalyst increases the rate at which
