Examples of experimental methods to determine the rate of a reaction, and the role of catalysts. How does concentration affect the rate of reaction? In this activity, we want to investigate how concentration affects the rate of the following chemical reaction: 2Mg(s) + 2HCl(aq) → 2MgCl(aq...
Learn about the rate of reaction. Understand the factors affecting the rate of reaction and see how catalyst, concentration, temperature and...
It is shown that optimum temperatures should exist where there is the highest rate of formation of a polymer of specified viscosity. However, these rates can be exceeded in the later stages of bulk polymerization or in emulsion polymerization where the bimolecular termination reaction is restricted ...

Chemical Reaction Rates Reaction rate refers to the speed at which a chemical reaction takes place, usually expressed as the change in concentration of reactants or products per unit time. Factors Affecting Reaction Rates: Temperature, Concentration, Catalysts, Surface Area ...
The reaction rates of the two enzymes at 45°C were higher than those at 37°C when the pH value was 8·2. The rate of the Maxatase catalysed reaction was more than that of Alcalase at 45°C. The activation energies were calculated and, as expected, it was found that the higher ...
