Give a detailed outline of any further work that could provide additional evidence for your conclusion. Solvent Effects The nature of the solvent can also affect the reaction rates of solute particles. This is due to the subjective nature of the experiment.

The rate of reaction is the rate of loss of a reactant or the rate of formation of a product during a chemical reaction. Background information: The dilution variable does not occur to the hydrochloric acid but it occurs to the sodium thiosulphate.

Some are moving fast some are moving slowly, and most are moving at some intermediate speed. Every now and then a couple of kids will run into each other.

What are the 4 factors that affect the rate of reaction

Reactions that do not take long to make a 3 Page Antonio Motta-Marques Dr Fowler Rates of Reaction Chemistry Sodium Thiosulphate and Hydrochloric Acid Reaction Rates product have a high rate of reaction, and reactions that take a longer time have a low rate of reaction. Introduction Although a balanced chemical equation for a reaction describes the quantitative relationships between the amounts of reactants present and the amounts of products that can be formed, it gives us no information about whether or how fast a given reaction will occur. Pressure The concentration of a gas is a function of the pressure on the gas. Only particles with enough energy to overcome the barrier will react after colliding If the reactants are uniformly dispersed in a single homogeneous solution, then the number of collisions per unit time depends on concentration and temperature, as we have just seen. Conversely, the concentration of a gas can be decreased by removing evacuating a gas from a fixed volume or by increasing the volume of the container. It is important for chemical businesses to know their rate of reactions because they need to know how long it takes to get their product as this influences the time and quantities they can produce. Both of these factors increase the reaction rate. There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: temperature, concentration of solution , pressure in gases , surface are of solid reactants , and catalysts In order to burn candle wax, the solid wax has to be melted and then vaporized before it reacts with oxygen. For example, rusting is a slow reaction; it has a low rate of reaction. Furthermore a colorimeter will be used to judge when the reaction has been completed. Most of the bulk chemicals produced in industry are formed with catalyzed reactions. Bond Strength Reactions involving the breaking of weaker bonds proceed faster than reactions involving the breaking of stronger bonds. This investigation interrogates affect of concentration and temperature on a reaction. Download
