Rate of Decomposition of Hydrogen Peroxide (H2O2) using various catalysts | KI, MnO2 and Fe(NO3)3 | Kinematics of Reactions

What is the effect of KI, MnO 2 and Fe(NO 3 ) 3 as a catalyst on the rate of decomposition of Hydrogen peroxide (H 2 O 2 ) at room temperature? INTRODUCTION Chemical kinetics discusses about the rate of a reaction and how various parameters such as temperature, catalyst, concentration and pressure affect the rate at which the reactant gets converted into a product in a chemical reaction. The decomposition of Hydrogen peroxide (H 2 O 2 ) is a reaction used as an example to explain the effect of catalyst on the rate of a reaction. In the past H 2 O 2 was used to clean wounds because the enzyme present in the blood, catalase, can decompose H 2 O 2 into water (H 2 O) and oxygen (O 2 ). The nascent oxygen released during the process is highly effective against bacterial growth in the wound [1] . This shows how catalase acted as a catalyst that facilitated the increased rate of decomposition of H 2 O 2 . The decomposition of hydrogen peroxide using catalyst h...

Can Wal-Mart compete with the e-giant Amazon in the Indian E-commerce platform? | SWOT Analysis | PEST Analysis | Customer and Competition Analysis

Introduction Founded in 1962, Walmart is an iconic American multinational retail corporation that operates across 27 countries in 11,503 stores. Walmart appeals to customers through its attractive pricing of products and the availability of wide range of products. Walmart is the largest company by revenue and the largest private employer. Walmart retail stores were a huge success in the US. They stepped into the e-commerce sector since 2000 by introducing walmart.com which allowed the US citizens to purchase goods from their online store. The competition between Wal-Mart and Amazon is one of the biggest rivalries in the business world. Both the business giants are in the run to dominate both the retail and e-commerce sector by expanding their roots across various countries and by acquiring other companies. In the e-commerce, Amazon’s numbers remain dominant because of their amazing web services and understanding of the Big Data in order to understand what the customers really want. T...

Mathematically Modelling the Post-Mortem Interval (PMI) | Sample IB Math Internal Assessment | Real-Life Application of Logarithms

Introduction Post Mortem Interval (PMI) is referred as the time that has elapsed after a person has expired [1] . PMI is a very reliable source of information that criminologists can use in order to solve or investigate a particular crime case. There are number of ways to estimate PMI, such as looking at the changes in the intestinal content, stage of invasion, blow fly larval development and so on [2] . These methods give more accurate estimation of PMI as it is useful in cases with both short PMI and long PMI [1] . But other methods such as Henssge-nomogram and the electrical or mechanical stimulation of skeletal muscles are only useful for short PMI because at one point of time the corps will attain the ambient temperature (room temperature) and stops cooling [1] . This method purely relies on the temperature factor, the cooling of the corpse. This method of death time estimation is based on the cooling of the corpse. From my prior knowledge I knew that the cooling of any object f...
