Through exploration of different studies on the topic, this paper presents current study from peer reviewed journals and how research advance the studies in chemical equilibrium and its application. The use of computer simulations in the study of simple and long chain chemical reactions has also beenexplored. Finally, the paper explores the law of thermodynamics and how it applies to chemical equilibrium. Introduction Chemical reactions involve reactants and interacting under certain conditions to produce a product. It refers to the process of transforming a set of chemical compounds or substances to another or others with totally different identities. It involves the changes of the position of electrons with regards to formation or breaking of the bonds while the original elements always remain the same. Since there is no change in the original elements present, a chemical reaction can always be represented by an equation. Reagents or reactants are the initial substances that participate in a chemical reaction thus during a chemical reaction, there is always a change. This is because the new products exhibit different properties. New products may have differences with regard to physical, biological or chemical properties depending on the nature of chemical reaction. Chemical reaction equation must have the starting materials (reactants), conditions for reaction, intermediate products and finally the end products. However, there are certain chemical reactions that are very simple and do not need to pass through the intermediate product in order to get to the final product. In a chemical equation, we may have two different types of chemical reaction as well. Chemical reaction that takes place according to concentration and temperature at a specific rate is called non spontaneous while one that require no other conditions except thermal energy is known as spontaneous. This principle forms the basis of calculating the rate of reaction as well as managing it. In this respect, non spontaneous reaction is very slow and thus requires an additional energy or catalyst to increase its rate. Objective of the Study The objective of this study is to explore different literature and explore the current studies in chemical equilibrium. This paper aims at exploring studies in academic journals mainly focusing on equilibrium constant and its application in different industries. Chemical Reaction Chemical reactions can be well illustrated by chemical equations. Chemical equations consist of two or more reactants on the left side and the resultant products of that particular reaction on the right side. An arrow at the middle of the equation always represents the direction of reaction which can be either to the right or to the left depending on the conditions. It is therefore important to note that most chemical reactions are reversible reactions. This is often represented by a double arrow which points on the both sides. The meaning of this is that products can also produce reactants depending on the concentrations and certain conditions. aA + bB cC + dD Irreversible reactions aA + bB cC + dD Reversible reactions The above equations shows the basic principle of a chemical reaction where A and B substances react to produce C and D substances. However, a, b, c and d ...Download file to see next pagesRead More

...CHEMISTRY QUESTIONS Presented Intramolecular forces operate within the molecules or fundamental units of a substance. This would include the attraction between positive and negative ions in a crystal of an ionic compound, the covalent bonds in a molecular substance as well as the covalent bonds linking atoms in a network structure, such as that of carbon (diamond).Metallic bonds are also classified as intramolecular forces (Frederick, 1979, P.63)Intermolecular forces operate between, rather than within, the molecules of a covalent substance. This would include the attractions exerted by one molecule of a molecular substance on another, such as the force of attraction between water molecules in ice ,the attractions between atoms... relative...

...Topic – Insert & Affiliaton) Question The n-butane molecule is represented by the following: Scientists have suggested a number of ways that organic molecules may be represented. Among them are the ‘Sawhorse’, ‘Newman’, ‘Fischer’, ‘Haworth’, and ‘Natta’ projections. In the Sawhorse projection the molecule C-C bond is viewed at an oblique angle. In the Newman projection the C-C bond is viewed from one end. The closer C is represented by a dot and the C further away as a circle. This projection makes it easier to view the torsional angles and is thus the preferred projection. The Carbon atom closer to the viewer is called the ‘proximal’ and the one further the ‘distal’ atom. The two extreme conformations of Butane are the...

...CHEMISTRY WORK: Q1.)Cyclic Voltammogram. Cyclic voltammogram makes use of 6m M Ascorbic acid in a 1M KNO3 matrix, the reference electrode is Saturated Calomel Electrode(SCE) , in this experiment the scan starts 0.00V(red) and Working Voltage is +o.80 V. A strong peak is reached at 0.35V relative to SCE indicating oxidation of dehydroascorbic acid. The Red Curve shows the first half of the scan 0.00V to 0.80V and back to 0.50V. Chemical Reaction: 2 electron Oxidation of Ascorbic Acid. The process is irreversible because the oxidation of ascorbic acid produces Dehydroascorbic Acid which is very unstable and it decomposes quickly before the reduction cycle can convert it back, thus due to Dehydroascorbic instability the process... , Atmospheric...

... Introduction to Chemistry: Analysis of Oxygen (O2) Introduction Oxygen is a chemical element that largely forms part of the atmospheric and is widely recognized with the sustenance of life and survival of organisms. It has a formula of O­2. As a chemical element, this substance has an atomic number of 8 and belongs to the chalcogen group on the periodic table; thus, making it build and possess certain significant characteristics for its operations such as being a highly reactive non-metallic element. Subsequently, oxygen is widely used as an oxidizing agent through its readiness to form compounds (in most cases oxides), with most of the atmospheric elements (Bauer, Birk & Pamela 145-149). Identification by mass sets this element... in...

.... Numerous changes that occurred in the fields of quantum chemistry, relativity, and uncertainty in the 1920s obligated chemists to review the currently held ideas regarding atoms and their structures. They reduced their reliance on physical models (that for instance described and an electron as a small particle, possessing an electrical charge and moving in a specific path at a specific speed and part of the atom) and placed more emphasis on mathematical models. They searched for mathematical equations that, when answered, would give the precise solutions for the mass, spin, speed, charge, as well as numerous other characteristics of the electron (Ghosh, et al., 2013).

.... The sensitivity of a luminescence based oxygen sensor is influenced by the properties of both the luminescent material and the oxygen permeable encapsulating medium. The natural lifetime of the excited state, τ0, also depends on the encapsulating medium. It is governed by the inherent physical and chemical properties of the materials used. Selectivity of a sensor is its ability to sense a radiation free from interference. Response time is a measure of how quickly the maximum signal change is achieved with UV changes. In addition, reversibility, long term stability and size are other factors influencing the overall performance of a UV oxygen sensor. It is important to note is the downward curvature in the Stern-Volmer...
