6) Orientation of reacting species. Factors that influence the reaction rates of chemical reactions include the concentration of reactants, temperature, the physical state of reactants and their dispersion, the solvent, and the presence of … The rate of a chemical reaction is affected by several factors like: 1) Concentration of reactants.

7) Surface area. 9) Nature of solvent. factors affecting the rates of sn1 reactions by isabella manlapaz isabella.manlapaz@go.tarleton.edu chem 2423 section 520 experiment june 20, 2018 executive A change in one or more of these factors may alter the rate of a reaction. 5) Nature of reactants. FACTORS AFFECTING RATE OF CHEMICAL REACTIONS . Raising the reaction temperature by 10 °C can double or triple the reaction rate. Learn about the Rate of Reaction and Factors Affecting Reaction Rate Here. Factors affecting the S N 2 reaction As we saw in the previous section, in the S N 2 reaction the rate of reaction depends on both the electrophile (usually an alkyl halide) and the nucleophile. The factors that affect reaction rates are: surface area of a solid reactant ; concentration or pressure of a reactant ; temperature ; nature of the reactants ; presence/absence of a catalyst. Chemical reactions proceed at different rates. The reaction rate decreases with a decrease in temperature. 4) Catalyst. The Rate of Reaction refers to the Speed of the Conversion of Reactants into Products in a Chemical Reaction. Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction. This is due to an increase in the number of particles that have the minimum energy required. In this lesson, you will define these factors, and describe and predict their effects on reaction rates. These include light intensity, the physical state of the reagents, and for some reactions the solvent in which the reaction is occurring. 8) Intensity of light. In practice, the rates of S N 2 reactions vary enormously, and for a practicable procedure we need to make sure that the reaction will happen at a reasonable rate. There are occasionally other factors, in addition to those detailed here, that can affect the rate of a reaction.
