Factors Affecting Rate of Reaction (GCSE Chemistry)

WebRates of decay are affected by a number of key factors. Temperature At colder temperatures decomposing organisms will be less active, thus the rate of decomposition remains low. WebIn GCSE chemistry, students will look at the different rates of chemical reactions. Some are fast (e.g. explosions or fireworks, which are sudden) and some are slow (rust is a very slow one). In this quiz for pupils in Year 10 and Year 11, we revise some of the factors which affect reaction rates. WebThere are several factors that can affect the rate of a reaction. These are: Concentration of the reactants in solution or the pressure of reacting gases. Temperature at which the reaction is carried out. Surface area of solid reactants. The use of a catalyst. Changes in these factors directly influence the rate of a reaction. css write text
