    if the heart and breathing rate will increase during exercise. It was hypothesised that if the amount of exercise (independent variable) increases‚ then the individual’s heart rate (bpm) and breathing rate (breaths-pm) (dependant variables) will increase when the environment in which the exercise is completed and a consistent and appropriate method of measurement for the dependant variables are kept constant. It was hypothesised that if physical exercise was increased‚ an individual’s heart and breathing

    Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

    In the experiment‚ the effect of light intensity on the rate of photosynthesis will be tested. Photosynthesis is the process in which autotrophic plants create their own food (energy) from sunlight. Photosynthesis involves three ‘ingredients’ or reactants‚ carbon dioxide‚ water‚ and light energy (sunlight). Carbon dioxide and sunlight come in through a leaf’s stomata which are tiny holes‚ and water is absorbed through their roots. When all of these reactants are combined in a plant’s chloroplasts

    Enzymes are a type of protein. They are catalysts meaning they speed up the rate of the reaction. Enzymes activity depends on the concentration of the substrate‚ temperature and the pH. The more concentrated the substrate is the more reactive the enzyme is. The optimal pH for an enzyme is 7.5 and the optimal temperature for an enzyme is 53 Celsius. Extremes in the temperature and the pH of an enzyme can denature therefore destroy it. The enzyme that is in this experiment is Amylase. Amylase is found

    was to find how certain factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction

    Chemical reactions can happen slowly or fast. The speed of the reaction rate can be changed. Some of the factors that can affect the reaction rate are surface area‚ temperature‚ and concentration and pressure. Surface area is the exposed‚ outer layer of a solid. Increased surface area increases reaction rate because more particles on the surface of a solid come in contact with the particles of another substance. For example‚ if you place a donut stick into water‚ the donut will react slowly with

    speed up the rate of reaction without itself being used up in the process. Enzymes provide an alternate reaction pathway by lowering the activation energy needed for a reaction to occur. For two molecules to react they must collide with each other‚ however‚ they have to collide with sufficient energy. Sufficient energy means that between them they have enough energy to overcome the energy barrier to reaction. This is called the activation energy. Even though enzymes can alter the rate of reaction

    Three Month Treasury Bills and The Variables That Affect the Rates Abstract This paper attempts to create two models that can predict fluctuations in three-month US Treasury Bill yields. Using both simple and multiple regression analysis‚ we analyze the independent variables traditionally associated with risk free U.S. money market interest rates including the Consumer Price Index‚ the Industrial Production Index‚ and the Unemployment rate over two periods‚ July 1990-March 2001 and March 2001-December
