reaction rate of the reaction plays an important role in the production of the ester which could affect the production of the ester. Esterification is a reversible reaction and thus this affects the amount of ester produced as ester hydrolysis changes it back to its reactants. Very little data is available on how does the carbon chain length of carboxylic acid and alcohol affects the rate constant and equilibrium constant of esterification. Thus‚ the research topic of this investigation is: How does

"To See What Factors Affect The Decomposition Of Hydrogen Peroxide By The Enzyme Catalase Which Is Found In The Liver" Introduction: Enzymes are biological catalysts. They speed up the chemical reactions which go on inside living things. Without them the reactions would be so slow that life would grind to a halt. Enzymes work by when a substrate molecule bumps into a molecule of the right enzyme‚ it fits into a depression on the surface of the enzyme molecule. This depression is called the

How Does the Change of Mass Affect the Rate at Which an Elastic Powered Car Accelerates? Research Question: How does the change of mass affect the acceleration of the Lego Car powered by elastic? Hypothesis: it was thought that the more weight added to the body of the Lego Car would slow down the initial acceleration‚ but the car would travel a longer distance due to increased momentum‚ which might overcome kinetic friction. Rationale: Some reasons of why that it was thought
