  • Reaction Temperature And The Rate Of Reaction

    1594 Words  | 7 Pages

    Discussion The experiment investigated the relationship between temperature and the rate of reaction for the reaction of iron (III) nitrate with sodium thiosulfate. The results show that the rate of iron (III) reacting forming iron (II) increases as the temperature of the solutions increases. Table 1 shows that when the temperature of the reactants is 4℃, it takes 54.173 seconds for the reaction to occur to the stage that the cross to appears. The time taken for the solution to reach the same transparency

    Background: A clock reaction generally involves a mixture of solutions that, after a certain amount of time, displays a sudden colour change. This process demonstrates chemical kinetics in action, which is the study of chemical processes and rates of reaction where the reaction rate is the speed at which the chemical reaction proceeds. It is dependent on several factors that rely on one basic underlying principle called collision theory. In order for a reaction to occur, the reactant molecules

    invaluable information relating to the rates of reaction. There are numerable applications of reaction rates, knowledge in this area is pivotal for industrial, commercial and research sectors. Thus, allowing them the ability to manipulate a variety of factors of chemical reactions with the use of reaction rates. In the scope of the kinetics of clock reactions, there is a range of information that can be obtained about reaction rates (Shakhashiri, 1992). A clock reaction is characterised by an abrupt colour

    Investigate if changing the concentration of an acid will change the rate of the reaction when marble is dissolved in hydrochloric acid. Apparatus Marble Chips Conical Flask Hydrochloric Acid Gas Syringe Delivery Tube Stop Watch Fair Test To make the experiment a fair test I will use the same amount of acid for each concentration. I will do this by using a capillary tube because they are very accurate. I will use 3g of marble in each concentration of acid. I will clean everything out before I

    temperature and the reaction rate, and that the highest temperature will have the fastest rate of reaction. The data also supports the hypothesis that as the concentration of Potassium Iodine increases so will the reaction rate, and vice versa for an increase in Sodium Thiosulphate concentration. The hypothesis that the Iron (II) ions will affect the reaction rate, and that the optimal amount will be about 0.1M of catalyst was partially supported. In Graph 1 the data shows an exponential rate of change as

    Title: How to increase the Rates of a chemical reaction Introduction: In this experiment we will be investigating how changing the temperature of the made up solution (copper chloride dihydrate and water) will impact the rate of a reaction when aluminium foil is dropped into it. We will determine this by selecting five different temperatures: 26 degrees, 36 degrees, 46 degrees, 56 degrees and 66 degrees and seeing at which temperature the reaction between the solution and aluminium foil produces

  • The Effect Of Temperature On The Rate Of The Reaction

    lab centralized on observing the effect that temperature has on the rate of the reaction 6I- (aq) + BrO3- (aq) + 6H+ (aq) 3I2 (aq) + Br- (aq) + 3H2O while also using calculations to determine the value of the rate constant and the activation energy at different temperatures. The activation energy of a reaction is defined as the minimum amount of energy required to make the transition from reactants to products. Given that the rate constant is proportionally constant for an experiment, it changes with

    Aim: The rate at which a reaction occurs, or takes place, is affected by various factors, such as the temperature at which the experiment is conducted in, the pressure which is given, the surface area which is exposed, use of catalysts, and the concentration. In this investigation, I would be investigating the affect of surface area, or particle size, in the rate at which a reaction occurs. Background Information: The more finely divided the solid is, the faster the reaction happens. A powdered
