Kinetic theory

The Kinetic Molecular Theory explains why gases behave the way they do. It explains how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container, depending on how many particles are in that container. If there are more particles then more collisions will happen creating more pressure. If there are less particles, then there are less collisions resulting in less pressure. Postulate #3 explains in…

known as matter. Energy is what can cause a change to matter. As energy cannot be created or destroyed, it gets stored or transferred. Kinetic energy is what a substance possesses due to it being in motion. The kinetic theory of matter states that matter is made up of small particles that are constantly in motion with spaces between them. (Andrew Rader Studios. Matter is the Stuff Around You. 1997-2015) There are 3 main phases of matter that are solids, liquids, and gases. The difference…

familiar with this we can predict what is propelling to happen in the experiment. Third, we will investigate Charles Law. This will aid us to understand how different temperatures can affect a basketball. Fourth, we will search how the bounce of the ball relates to its air pressure. Next we will consider the Kinetic Theory of Gases. This theory can help us learn what the molecules themselves are doing inside the object (basketball). Finally, we will explore effusion. Although it branches off the…

at which a reaction occurs, the amount of kinetic energy needed to break bonds is a predetermined value. This fixed value is known as the activation energy, or Ea, and can only be altered by the addition of a catalyst. However, if certain variables are changed, the number of successful collisions between reactants can be increased. In this experiment, a single displacement reaction occurs when hydrochloric acid is combined with magnesium to form magnesium chloride and hydrogen gas. Mg (s) +…

Trayc Poppenhager May 5, 2015 TA: GK Chem 341 Thermodynamics and Kinetic Control Goal: The overall goal of this experiment was to learn and observe about kinetic and thermodynamic control of different reactions by noticing which product forms faster or slower and possibly which reaction is more stable than the rest of the reactions. Significance: Organic chemists find using kinetic and thermodynamic control useful because they use the concept of the reactions to figure out…

of this experiment is to identify the rate constant in kinetics reactions during the t-butyl chloride convert into hydrolyzed. Theory Kinetics reaction analyzes the how fast the chemical reaction occurs when two solution mix together. Chemical reaction is changing their properties and reagents concentration which create new products. There is a titration method to check the kinetic reaction. For example, of chemical equation as aA + bB → cC+ dD This equation describes the general term in rate…

Research Question How does the change in hydrochloric acid concentration affect the rate of reaction between sodium thiosulfate (Na2S2O3(aq)) and hydrochloric acid (HCL(aq))? Background to the Research question Collision Theory Back in 1916, scientists William Lewis and Max Trautz proposed the collision theory, which qualitatively explains how chemical reactions take place and why reaction rates change for various reactions. Chemical reactions involve collisions amongst reactant particles or…

Chemical kinetics are governed by the mathematics of systems of differential equations (Thermodynamics and Kinetics). This means that the rate of any chemical reaction is determined by the type, and amount, of reactants present. Note the rate of a reaction is how fast it occurs. Furthermore, such rate equations can either be distinctively linear or non-linear when graphed. Non-linear equations are supposedly more complex as they generally react to small changes within its parameters…

Figure 1 shows that the temperature increases the amount of foam being produced, to a certain extent. The orange box showcases the average reaction rate, which was calculated to make an assumption of the volume of foam produced within two minutes. The reaction rate was calculated by dividing the volume of foam by the number of minutes. Reaction rate (ml/min) = final foam vol – 17ml (10ml H2O2 + 5ml Sodium iodide + 2ml detergent). In Table 1, it is evident that the difference between room…

will occur. In both cases something is being increased, for example, placing solutions A and B in the warmed water increases the solution's temperature which causes the particles to collide more frequently due to kinetic molecular theory. By increasing the concentration of the reactants increases the rate of the reaction. (http://chemguide.co.uk/physical/basicrates/concentration.html)…
