dioxide‚ had a greater reaction than the other test tube. Which simply contained 10 mL of 3% hydrogen peroxide. The factor that affected the reaction rate was that the manganese was seen as a catalyst. The reason collision theory relates to this experiment is due to the fact that the catalyst creates a higher activation energy and this causes more collisions‚ which increases the reaction rate. In the second experiment‚ the Alka Seltzer tablet was

The effect on rate of an enzyme catalysed reaction by different objectives which include effect of substrate‚ temperature‚ ph and effect of a competitive inhibitor phosphate ions. This is determined by the reaction of hydrolysis by p-nitrophenylphosphate (PNP) as a substrate by the enzyme phosphatase. Abstract The hydrolysis of p-nitrophenyl phosphate has been studied in human red blood cells. To see if hydrolysis was related to the functioning of the sodium pump. Acid phosphatase catalysis’s

The Correlation between the Diffusion Rate of a Substance and its Molecular Weight ABSTRACT To test the effect of molecular weight on the rate of diffusion‚ various experiments were performed. One of which is the glass tube test wherein cotton balls of the same size were moistened in two different substances (NH4OH and HCl). These cotton balls were plugged at each side of a glass tube. After some time‚ formation of a white ring occurred. The white ring‚ in fact‚ is a product of the reaction between

ISOMERIZATION OF AN ALKENE Martin‚ Marilen1‚ Lovenia‚ Melden D.2 1Professor‚ School of Che-Chm-BE-MSE‚ Mapua Institute of Technology; 2Students‚ Chm145L/A41‚ School of Che-Chm-BE-MSE‚ Mapua Institute of Technology ABSTRACT The experiment was conducted to accomplish the following objectives. The first objective aims to synthesize an isomer of alkenes. This was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid

Abstract: This lab tests how temperature and pH affect how enzymes will function. The lab showed that temperature will denature an enzyme when past its optimal working temperature and won’t denature in cold temperatures‚ but have slowed molecular activity. pH will also have an affect on an enzymes efficiency‚ when out of optimal pH the enzyme will not function as it is supposed to and if to far out of the optimal pH the enzyme will change shape and no longer work. Enzymes also showed to be reusable

Introduction This project is about analysing the factors affecting the demand of mobile telephone products. The case study that will be included is the current state of the UK mobile telecommunications market. The operators to be examined are the four major operators in the UK: BTCellnet‚ One2one‚ Orange and Vodafone. The case study for this project will be based on the current state of the UK mobile telecommunications market and the performance of its four consumer operators. Before this can

Biological Factors in Crime Not many want to believe there is any such thing as a "bad seed;" that heredity can make criminal behavior unavoidable and inevitable for some individuals. Of course‚ bio-psychologists do not believe that genetic or physiological components

The purpose of this practical is to investigate how the pulse rate of humans changes when they exercise. Someone who is physically fit can supply their muscles with enough blood‚ carrying glucose and oxygen‚ for an activity at a lower heart and breathing rate. The fitter you are the lower your resting heart rate. You and your classmates will be the humans investigated. SAFETY: If you know you have any condition that affects you doing exercise‚ please make sure your teacher knows before you start
