Reaction rate constant

The Kinetic Molecular Theory explains why gases behave the way they do. It explains how gas particles are in constant motion and create collisions that results in pressure. The theory is split up into four different postulates. Number one explains how gases are made up of tiny particles. To prove that those particles take up space, postulate #2 tells us that the particles collide with each other and those collisions make pressure. Pressure can either expand or shrink a flexible container,…

There are small particles in the air called aerosols. They are found in fog and smoke. These particles become larger in size if two processes occur. The first process is water vapor accumulating onto a particle. The next process is cool, rising air supporting the particle. Once the aerosol particles are large enough, they become cloud droplets that will have a different mechanism of growing. Cloud droplets grow differently because they are larger in size. Instead, they grow by a new process…

therefore we measure weight as our numerical data. My hypothesis was that the 10g dilution of salt would have the gummy bear with the largest mass. This was because diffusion is the process where the molecules of both substances interact, with a constant kinetic energy. Therefore because the salt would increase the mass of the water, it would in result also increase the mass of the gummy bear because of the kinetic energy that interacts with both sets of molecules. In our planning stages we…

Even though Amylase can get denatured at high temperatures, a slight increase in temperature, should increase the rate of amylase reaction. Research title The effect of temperature on amylase activity. Word count-1025 Background research Enzymes are catalysts which speed up reactions in living organisms. Enzymes function by decreasing the activation energy for a reaction. Amylase is an enzyme found in human saliva and catalyses the hydrolysis of starch .Amylase like all other…

the reaction. We then added KMnO4, drop by drop, to see how much hydrogen peroxide remained in the solution, which was our dependent variable. An enzyme is a catalyst, and it has two fundamental characteristics that it is known for. One of these things it that it can increase the rate of a chemical reaction without being changed or destroyed in the reaction. The second is that they don’t alter the chemical equilibrium between the reactants and the products while they speed up the reaction. …

the action of enzymes to carry out the reactions of life. According to the text in Campbell Biology, enzymes are biological catalysts. These globular proteins speed the rate at which metabolic processes occur by lowering the activation energy or the energy barrier required to transform reactants to products. Each enzyme is specific, each containing active sites destined for a substrate. Substrates are the reactants or starting materials of chemical reactions. The binding of substrate to…

Enzymes are a biological catalyst. When a chemical reaction is taking place the enzyme works to lower the activation energy of a reaction. The activation energy is, the amount of energy that is required in order for a reaction to take place. Enzymes bind to reactant molecules. The enzymes hold these molecules in a way that makes the processes of the chemical bond-breaking and bond-forming take place more readily. A reaction can be either energy-releasing or energy-absorbing. Enzymes have no…

A chemical reaction’s rate is described by the amount of product formed. Substances that increase that rate are called catalysts. Catalysts are often proteins called enzymes. Enzymes change the pathway of the reaction between the products and the product. However, enzymes don’t alter the starting or ending points. Enzymes are effective by reducing the activation energy. The enzyme tyrosinase is located in melanocytes. These are cells that produce the pigment melanin. Melanin gives skin, eyes,…

This experiment monitored the synthesis of uridine from the deamination of cytidine through separating the contents of the reaction mixture using HPLC (High-performance liquid chromatography) at various time intervals since the start of the reaction. Cytidine and uridine standards are ran and the output of the HPLC will show two peaks based on the retention times of each compound. Identified the peak with the retention time of 2.422 minutes is cytidine and uridine has a retention time of 2.716…

affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different enzyme concentration at 0…
