The Physics Of Chemical Kinetics - 1921 Words

Investigations into the mechanics of chemical kinetics can reveal invaluable information relating to the rates of reaction. There are numerable applications of reaction rates, knowledge in this area is pivotal for industrial, commercial and research sectors. Thus, allowing them the ability to manipulate a variety of factors of chemical reactions with the use of reaction rates. In the scope of the kinetics of clock reactions, there is a range of information that can be obtained about reaction rates (Shakhashiri, 1992). A clock reaction is characterised by an abrupt colour change following an established time lag (Lente et al, 2007). The induction period in a clock reaction is a result of low concentrations of the clock chemical (i.e. the chemical that enables the final reaction). The induction period ends after the total consumption of a limiting reagent, which initiates a short increase in the rate of product formation, resulting in a visible colour change (Schmitz, 2010)(Lente et al, 2007). The reaction rate of clock reactions is subject to factors including temperature, concentration, catalysis and inhibition. These factors can be manipulated, thus changing the length of the induction period in a ‘clock-like’ manner (Shakhashiri, 1992). Changes in the rate of reaction can be described in terms of chemical equilibrium. â€Å"Chemical equilibrium is a state in which the forward and reverse reactions take place at the same rate† (Wilbraham et al, 2002).

A discussion concerning the various properties of a substance that determine its heat capacity is followed by a description of some of the various sources of heat. Finally, an analysis concerning how the study of heat relates to the kinetic theory of matter is followed by a summary of the research and important findings in the conclusion. Review and Analysis What is heat? Interestingly, heat is not static energy but rather by definition is moving from a hotter object to a coolerRead MoreThe Theory Of Heat : The Natural Sciences Span Over A Wide Range Of Phenomena1126 Words   |  5 Pagessciences. Scientists have been allowed to research these phenomena due to underlying connections between subtopics. In physics one can view many underlying connections between different subtopics. For example; in thermodynamics. Thermodynamics is a branch of physical science that deals with the relations between heat and other forms of energy such as mechanical, electrical or chemical energy. More importantly, heat itself and its relation to energy and work done on a system. Many people have misconceptionsRead MoreNewtons Laws of Motion858 Words   |  3 PagesAnother concept of Physics is moving water. For example, flushing the toilet, waterfalls and dams. Flushing a toilet is a great example of transferring energy. Usually on most toilets there is tan on the back of it filled with water. Water that is stored is a great example of potential energy and no kinetic energy. Once toilet is flushed, it gives the water momentum. From waterfalls and dams we can produce hydropower. It is a renewable energy source that converts kinetic energy fromRead MoreHow The Shape Of Ice Affect How Fast It Melts?1254 Words   |  6 Pagesenergy, it is then in liquid phase of H2O, called water, which can then be broken down in the smallest unit; atoms. Professor John Blamire of brooklyn.cuny.edu describes a single water molecule, the smallest part of a chemical element or compound that still shares the same chemical properties as defined by whatitis.com, as two slightly positive hydrogen atoms and one slightly negative atom together forming a hydrogen bond. In a water molecule, hydrogen atoms have a single electron and oxygenRead MoreCh 1 Each different scientist made an impact in some way to the origins of an atom.

Boscovich had a different perspective on what an atom could look like. He set more examples which made it more visual. Ch 2 John Dalton was persuaded to start a journal on weather observations by his friend, John Gough. He observed the different chemicals in the atmospheres. This helped him explain why certain chemicals reacted a way and heRead MoreNotes On Order Disorder And Energy845 Words   |  4 Pagesreactivity to explode or cause a chemical reaction. More so, the position of an object, can assist us in building objects of great mass to see if the potential energy is strong enough to break any of the supports. Subsequently, if someone wanted to jump from a certain height, the force of gravity, and the height the person is jumping from can affect his legs because the impact could cause damage. Additionally, Potential Energy is used in many calculations in physics force, energy analysis, and mechanicsRead MoreEnergy And Energy Of Energy1140 Words   |  5 Pagesenergy, or stored energy; and Kinetic energy, or energy is a form of potential energy and it is possessed by things such as food, fuels, and batteries. Energy is the ability to cause changes in matter. It can exist in many different forms. Energy can change from one form to another. There are six forms of energy: mechanical, chemical, electrical, light, thermal, and sound energy. Another form of energy is nuclear energy. Mechanical energy is the energy of movement. Chemical energy is energy that is storedRead MoreTaking a Closer Look at Phisics948 Words   |  4 Pages Physics. Not something you really hear every day. It’s not something you really want to hear either, right? Why is it that when we hear the word physics, it’s just a major turnoff. People may even hear the word and just think â€Å"get me out of here†, even though they may not have the slightest clue of what it’s about. Some people do have a slight clue and think molecules or gravity, atoms or Bohr, laws or life, and still may not quite grasp it, but at least have a slight clue. Others, think wastedRead MorePhysics of Microwaves Essay981 Words   |  4 Pages Physics of Microwaves Microwaves are used in our everyday lives but most most people dont realize that physics plays a large and important part in the simple household item.
