Reason for choosing Antoine Lavoisier
Antoine Lavoisier

Antoine Lavoisier transformed chemistry to a large extent. Lavoisier named elements such as carbon, oxygen, and hydrogen. He also discovered the role of oxygen in respiration and combustion. He found out that water is a compound, which is made up of hydrogen and oxygen atoms. Lavoisier established that sulfur is an element, and revolutionized chemistry from qualitative science to quantitative science (Goedecke, par. 2, and par. 3). For these reasons, studying his life and work is interesting. 

History of Antoine Lavoisier
Lavoisier was born on 26th August 1943 in Paris, the capital city of France. His mother passed on when he was five years old, leaving him in wealth, which his mother generated from butchery business. Moreover, Lavoisier’s father was practicing law in Paris parliament (Goedecke, par. 1). He pursued his education at College des Quatre-Nations, a branch campus of University of Paris (Goedecke, par. 1). In the last two years of his study at the college, he pursued sciences. Even though he was interested in sciences, at the age of 18 years, he joined law school to pursue law. He reached this decision after his father told him that science was a hobby, not a serious profession. He studied law for two years and was awarded a bachelor's degree in law.
A year after graduation, he acquired a license to practice law, but did not practice law thereafter. When studying for his law degree, Lavoisier was still interested in science. As a result, he attended science classes in addition to his law classes. He published his first science paper the same year he acquired a law license. In the same year, he also read a scientific paper to the top French Academy of Science (Goedecke, par. 1). 

What made Lavoisier Famous?
The discovery of carbon forms and naming carbon is one of Lavoisier’s works that made him famous. In 1772, Lavoisier and other colleagues purchased a diamond and put it in a sealed jar. They then magnified the sun's rays on this diamond. Surprisingly, the diamond burned and vanished. Lavoisier found out that the weight of the jar did not change after the disappearance of the diamond. The observation enabled him to justify the law of mass conservation. He realized that burning charcoal or diamond generated the same gas that is today referred to as carbon (IV) oxide. He concluded that diamond and charcoal are distinctive forms of the same element, which he named carbon. 

The understanding of oxygen and combustion is another famous work of Lavoisier. In 1772, people did not understand the concept of the burning process. Fortunately, it was until the sulfur or phosphorus burning discovery of Lavoisier in 1772 when people grasped the concept of the burning process (Arthur, 351). Lavoisier noted that burning either sulfur or phosphorus produces acidic products. He also found out that the products weighed more than the original Sulphur or phosphorus, implying that phosphorus or sulfur combined with a certain unknown substance in the air to generate acid products.
The identification of this substance became intense when Joseph Priestley came to Paris and briefed Lavoisier about the gas that is released during the decomposition of mercury oxide (Goedecke, par. 4). The information encouraged Lavoisier to research more about the substance. In 1779, he named the substance oxygen and discovered that its presence in the air was about 20%, and was responsible for combustion and respiration (West, L775). As a result of this discovery, he concluded that oxygen combined with sulfur or phosphorus burned in air to form sulfur oxide or phosphorus oxide.

Roles of Sodium Carbonate when Extracting Caffeine from Tea Leaves

Image
A student failed to add sodium carbonate (Na 2 CO 3 ) when extracting caffeine from tea leaves with hot water. Though, high yield of caffeine was produced. The crystals melted at temperatures between 202  and 214 degree  Celsius. Explain. This happened because sodium carbonate did not interfere with the caffeine content of the tea leaves. Sodium carbonate (which is a base) deprotonates the phenolic hydroxyl group (-OH) (acidic) of tannins rendering them anionic. Hence, making them highly soluble in water, but parsimoniously soluble in methylene chloride. So, if sodium carbonate is not added when extracting caffeine with hot water, the extracted caffeine would also contain tannins. Additionally, sodium carbonate is added during the extraction to keep caffeine (an alkaloid which is an organic base)  in a free base form. It prevents caffeine from reacting with available acid available, which may lead to the formation cation. It reacts with a phenolic h...

Arrhenius equation: Increasing temperature increases the rate reaction

Image
The rate of reaction of a particular reaction often increases as one increase the temperature. However, how can this belief be proved using Arrhenius equation? According to the Arrhenius equation, the rate constant (k) is obtained by the ratio of Ea to RT, in which Ea denotes required energy while RT is the available thermal energy. The Arrhenius Equation is given by: k=Ae - (Ea/RT) When Ea is larger, it results in slower reactions. On the other hand, when RT is large, it leads to faster rate of reaction. Larger Ea gives smaller rate constant k, but larger RT produces larger rate constant (k). Larger rate constant increases the rate of reactions.  By using Arrhenius equation, one can easily see that when the temperature is increased, the rate constant will also increase. Let us consider these two scenarios. In the first scenario, Ea=120,000 Joules/mole, R=8.31 mol -1 K -1 , and K=373K.In the second scenario, Ea=120,000Joules/mole, R=8.31 mol -1 K -1 , and K...
