that as (the first variable being tested), the concentration in the solution is changed and it becomes more dilute, this will result will be a slower rate of reaction. Therefore, it is also hypothesised that the addition of a catalyst will cause the rate of those reactions to speed up, was proven correct by the results of this experiment, in that the changing of the concentration and the addition of a catalyst changed the speed at which the reaction occurred. The results from both Part 1 and Part
Rates of reaction are important to daily life because life would not be supported exist if a reactions occurred too slow or too fast (Anon, 2016).Reaction rates are extremely important to many industries as they dictate the rate of production of daily products. In the effort to meet demand and safety standards, optimisation of rates of reaction becomes one of the most important subjects to control and study. Rates of chemical reactions depend on the nature of the reactants, the reaction temperature

OBJECTIVE: The experiment was carried out to investigate the effects of the increase in the enzyme concentration on the rate of reaction. By using self investigative and experimental skills, the experiment was done in order to determine how the rate of reaction will be altered, whether it will increase, decrease or remain constant when the different concentration of enzymes added. INTRODUCTION: Enzymes are produced naturally in plant, animal, and microbial cell. There are thousands of different

by the concentration of starch, or whether the results I got were due to the amounts of solution used. This would make both my results and conclusion invalid and unreliable. I also made sure that the temperature of the water bath was at the correct temperature and I kept on checking the temperature of both my amylase, and starch using a thermometer. I made sure both solutions were at the same temperature at all times throughout my experiments, so that temperature would not have an effect on my results
The Effect Of The Concentration Of A Substance On The Rate Of Reaction Year 9 Chemistry Assignment Term 3 Introduction The purpose of this experiment was to measure and interpret the effect of a chemical concentration on a reaction rate. A collision theory is a theory proposed by Max Trautz and William Lewis that states: qualitatively explains how chemical reactions occur and why reaction rates differ for different chemical reactions (Wikipedia, 2015). An example of collision theory is when two
Summary This experiment will measure the rate of oxidation of iodide ions by persulphate ions to derive the rate law for the reaction. Starch will be added to the reaction to facilitate the measure of time during the reaction. The reactant solutions will contain (NH4)2SO4 and KI, represented as: (NH4)2S2O8 + 2KI -> I2 + (NH4)2SO4 + K2SO4 This can be simplified to: S2O82- + 2I- -> I2 + 2SO42- These equations can only be carried out and be visible after the iodine has completely
Effect of Reactant Concentration on Reaction Rate Research Question What is the effect of reactant concentration on reaction rate? Aim To investigate the effect of reactant concentration on reaction rate. Introduction This experiment is based on the effect of reactant concentration on reaction rate. "Reactant concentration is the amount of the chemical and the number of molecules being used and the higher the amount of reactant the higher the reaction rate is and the lower the amount of
relationship between temperature and reactant concentration on the rate of reaction for the hydrolysis of tert-Butyl Chloride, and to determine the validity of the proposed mechanism for the reaction. It was hypothesised that measuring the kinetics of this unimolecular substitution reaction would demonstrate the reaction rate for the hydrolysis of tert-Butyl Chloride utilising acetone as the solvent which should increase with both its increased concentration and temperature, to produce the product tert-Butyl
