Chemical equilibrium

photons resulting to higher absorbance values. All deceleration curves except for our control variable are gradually increasing as time is passing by and levels off reaching equilibrium. A molecular explanation for the results in figure 1 is that polyphenol oxidase is a catalyst that lowers the activation energy, which speeds up chemical reaction, to reach a transitional state leading to the formation of pink/gold melanin (Brooker (2014). If the activation energy is not lowered it will act as a…

Distillation is the most widely used separation process in the chemical industries. The separation of mixtures by distillation depends on the relative volatilities between the components. The greater the relative volatilities, the easier the separation. DME can be used as an alternative raw material when it is converted to gasoline. The DME is converted to gasoline range hydrocarbons over a zeolite catalyst. In the gasoline production reaction, some reactions cause unwanted components which may…

more focused on the study of the properties of matter as well as the interaction between various types of matter. The interaction is often facilitated by the reactions that involve either electron loss or electron gain, as described by the American Chemical Society (2014). Unlike other sciences, such as physics, chemistry doesn’t put more focus on the nuclear part of the atom, and any other subatomic realm. Perhaps it’s important to emphasize that chemistry is a science, and thus the procedures…

The concentrations of difference between the membrane phase and feed phase based on the mechanism of mass extraction. In the case of feed solution represented radioactive simulated waste solution and dissolved in 0.5M HNO3. In the feed phase decreasing with H+ concentration. pH values at 2.5 into 5.5 in the feed phase. Fig,s(5a-5c). Shown the effect of hydrogen ion concentration in the feed phase and studied of pH range 2.5-5.5 for 0.5M HNO3. Stripping solution of 0.05M of EDTA. Initial…

This is because the oil molecules are much bigger than water molecules that has more surface to stick to one another because more energy is needed to overcome the chemical…

the activation energy, thus speeding The reaction rate. Most of the reaction rate can be improved hundreds of times by enzyme catalyst. Enzyme as a catalyst itself is not consumed in the reaction process and does not affect the chemical equilibrium…

According to the American Chemical Society, many properties of clothing ranging from color to warmth to clothing’s elasticity is the work of a textile chemist (2016). Textile chemistry allows us to create synthetic fibers to produce clothing that is finely tuned to a certain situation…

fastest because the higher heat sped up the chemical reaction. This experiment relates to the diffusion experiment because the higher temperature in both experiments produced the fastest results. In the diffusion experiment, the highest temperature allowed the food color molecules to move at a faster rate, allowing the food color to diffuse in the water the fastest. Like the diffusion experiment, the higher temperature in this experiment produced a faster chemical reaction, allowing the Alka…

Abstract. The theoretical treatment of the equilibrium structure of the derivatives was based on the DFT method using the functional B3LYP with the base 6-311 ++ G (d, p). To distinguish the molecular electrostatic potential surface (MESP), we used the principle of HSAB (Hard Soft Acid and Base), in order to have the centers of activity of a molecule and the effects of substitution on the systems of pyrazolooxazine. These have anti-inflammatory activities. In our work, we have applied methods of…

The Earth is covered by about 70% of water and naturally, water is the only material that exists in three different states (solid, liquid and gas). This highlights that water is an important component as a chemical substance and this is due to its unique properties. Structure of water is one of the main features of water that allows it to carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has…
