    ZP catalyst as a function of time for the reaction of phenol alkylation with TBA at 80 °C, mole ratio of phenol to TBA of 1:2. The %conversion of phenol increased with reaction time up to about 210 min. In the early stages of the reaction, the first 60 min, phenol conversion was 30% and increased slightly up to 47% after 120 min. We assume this may be due to the fact that as tert-butanol was consumed in the reaction, fewer molecules were left in the reaction mixture and more time was required to generate

    The rate of a reaction would be the change of concentration of a reactant divided by the time (Green & Damji 161). The rate law is an expression deduced to show the relation of rate to the concentrations of the reactants in a chemical reaction. The rate law equals the rate constant, multiplied by the concentration of the reactants raised to their respective reaction orders (Green & Damji 170). The rate law of the equation given above is: k is the rate constant (given in M/sec or sec-1 or M-1sec-1)

    RATES OF CHEMICAL REACTIONS REACTION ORDER FOR IODATE ION OBJECTIVE: To determine the order of a KIO3-NaHSO3 reaction with respect to the iodate ion. To determine a difference on the rate of the reaction when the solution is 10oC higher than a room temperature. BACKGROUND: The rate of a chemical reaction is the speed at which reactants are converted to products. Some reactions are very fast and

    Enzymes Enzymes are the sparks that start the essential chemical reactions our bodies need to live. They are necessary for digesting food, for stimulating the brain, for providing cellular energy, and for repairing all tissues, organs, and cells. There are three types of enzymes: metabolic enzymes, digestive enzymes, and food enzymes. Metabolic enzymes catalyse, or spark, the reactions within the cells. The body's organs, tissues and cells are run by metabolic enzymes. Without them our bodies

    Effect of Temperature on Rate of Reaction of Catalase Introduction This investigation was in an attempt to try to find out how varying the temperature can affect an enzyme. The enzyme used was catalase which breaks down Hydrogen Peroxide, this gives off water and oxygen as effervescence. This effervescence is what is used to measure the reaction rate of the catalase. The optimal heat for enzyme activity is proven to be 37oC as anything above this denatures the enzyme. Denaturing is where

    Experiment on Rates of Reaction Rates Of Reaction: The time taken for a reaction to take place. The speed of the reaction has a big effect on the time, e.g. time taken for concrete to set may take hours, days or even weeks. Factors: Temperature: The temperatures during the rates of reactions are important because they can change how quick the reaction takes place. · Increasing the temperature will cause the particles to move faster, with more energy. · They will therefore collide

    that Influence the Rate of a Chemical Reaction Aim The aim of this experiment is to find out what affects the rate at which a reaction occurs between sodium thiosulphate and hydrochloric acid. I want to find out whether and to what degree varying the concentration of sodium thiosulphate has any effect on the rate of reaction. Prediction I predict that the greater the concentration of Sodium Thiosulphate solution the faster the chemical reaction will take place. I think the concentration
