The purpose of this lab is to learn how to write law expressions, determine orders by graphs, and calculate rate constants. By determining the number of drops of sodium hypochlorite necessary to make a diluted food dye change to colorless in less than three minutes helps calculate the absorbance which can then be analyzed to find the pseudo rate constant and eventually leading to the rate constant and the rate law. The results show that the m and n are both 1st order which makes the overall order of the blue dye 2nd order.…
In order to compare the two reactors used in our experiment, a simplified global kinetic model was used to describe the DRM reaction behavior in different plasma reactor. This model was already used by authors in the field of pollutant removal by using a plasma reactor [15, 21–23]. It is generally accepted that free radical processes are the main mechanisms in non-equilibrium plasma reaction [21, 24-25].…

In the “Crush the Can” lab, we took an aluminum can, heated up some water in it, and turned it upside down into a tub of ice-cold water, crushing it with pressure. The movement of gas particles was a crucial component of this experiment. After the can was placed onto the hot plate, as the water heated up, the gas particles inside of the can started to move faster due to the relationship between temperature and the average kinetic energy, or average motion energy, of the gas particles. As the temperature increased, so did the speed of the particles inside of the can. Particles of water obtained sufficient energy to turn into water vapor, and the particles of water vapor displaced the original air inside of the can. As the number of elastic collisions…
Be aware that all molecules have kinetic energy, which means that is an active energy that is always in motion. Molecules move in all different ways and this create an evenly distributed movement which is best known as diffusion. Diffusion is the movement of molecules from a region of their higher concentration to a lower concentration.…

Kinetic energy is increasing between letters A-B, C-D and E-F. Based off the observations, in phase A-B Tert-Butyl Alcohol stays a solid, in phase C-D Tert-Butyl Alcohol stays a liquid, and in phase E-F the chemical stays a gas. This is observed at the particle level because temperature is a measure of Ek; the temperature is increasing which increases kinetic energy. Since Ek is the energy of motion, the particles would increase their velocity and the number and force of collisions. However, the particles would not increase their spacing since the phase potential energy remains constant during each of these three phases.…
1.According to the kinetic theory, both the particles in gases and the particles in liquids have kinetic energy. This energy allows the particles in gases and liquids to flow past one another, as shown in Figure 13.5. Substances that can flow are referred to as fluids. The ability of gases and liquids to flow allows them to conform to the shape of their containers.…
The years after the war brought times of disagreement and argument. The United States worked at this time to contain and control the spread of communism. During the years of WWII and the Cold War this idea was prominent and an issue America thought must be solved. Their were two strong attempts to fight communism. These attempts were the Truman Doctrine and the Marshall Plan. These ideas go hand in hand making them "two halves of the same walnut."…
According to (Tillery, Enger, & Ross 2009) it defines Kinetic theory of matters as the collection of assumptions that all matters is made up of tiny atoms and molecules that interact physically, that explains the various states of matter and that have an average kinetic energy that defines the temperatures of a substance. (p720-21) Many early Greek philosophers believed substances are…
When something is able to change its environment or itself, it has energy. When you think of energy, you might think of action- or objects in motion, like the baseball that shatters a window. There are different forms of energy. Turn on an electric light and a dark room becomes bright. Turn on a music player and sound comes through your headphones. In both situations, energy moves from one place to another; effect and reaction. The two different types of energy are kinetic and potential energy.…
