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
Rate equation and order of reactant: The rate of reaction is defined as how fast the reactant is converted to the product and it is measured in moldm-3s-1 Rate=(change in concentration(〖moldm〗^(-3)))/(time taken (s)) , the unit of rate = moldm-3s-1 Rate = k [A]x [B]y [C]y Orders of the reaction must be taken in to account when writing a rate equation. Where A, B and C are reactant, x, y and z are the orders of the reaction with respect to A, B and C. In my investigation I will vary the concentration
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 must collide
Chemical Background Hydrogen peroxide is a by-product of many reactions that occur within the body – however, it is toxic so needs to be broken down. The equation for this decomposition is as follows: 〖2H〗_2 O_2 → 〖2H〗_2 O+ O_2 In the body, this reaction can be catalysed by the enzyme catalase. Catalase is not removed or used up in this reaction, and speeds up the rate of reaction. It is acting as a catalyst. The decomposition can be catalysed by other catalysts, however, and this is the basis of

Aim To investigate the effect of temperature, concentration of reactant and particle size on the rate of reaction Introduction Rate of reaction is the amount of reactant used up per unit time. Reaction occur only when the molecule of the reactant collides with a proper orientation along with the energy equal to or greater than the activation energy. Some of the factors that will affect the rate of reaction are: A: Temperature • The rate of reaction increases as the temperature increases • The particles
experiment is to discover the rate reaction of the Landolt Iodine Clock. This reaction is used to display the chemical kinetics in action, it was discovered by Hans Heinrich Landolt in 1886. It is where two colourless solutions are combined and no instant change appears but over a certain time delay depending on the factors it will instantly change to a dark blue. The Chemical kinetics of the reaction refers to the rate of the reaction. Different reactions occur at different rates, for example if it is a
this experiment was to determine the role of various chemicals in a reaction, to determine how concentration affects the rate of the reaction, and to determine how temperature affects the rate of the reaction. Both concentration and temperature greatly affect the rate at which the reaction occurred, and changing the concentrations of the reactants or the temperature at which the reaction occurred changed how quickly the reaction took place. The scientific aim of this experiment was to determine which
is essentially the study of reaction rates and how they can be affected. Factors such as concentration, pressure, temperature, and enzyme activity, are commonly tested regarding their impact on the rate of a reaction (Khan Academy, 2017). It is important to recognise and understand the components that affect the rate of chemical reactions as this allows control over the reaction process. Chemical reactions progress naturally at different rates. A chemical reaction involves the rearrangement of
