affecting Rates of a Reaction (Kinetics) KINETICS DESIGN LAB Research Question: Does the concentration of Potassium Iodide (KI) affect the rate of its reaction with hydrogen peroxide (H2O2) (of a fixed concentration)? Introduction: There are several factors that affect the rate of a reaction. Some of them being Pressure (if the reactants are Gases)‚ Temperature‚ Presence of a Catalyst‚ Surface Area of the reactant‚ and Concentration. According to the Collision Theory‚ during a reaction‚ particles

hypothesis proposed that if a small amount of salt was added to the reaction‚ then it cause the rate of the reaction to speed up‚ but if too much salt was added‚ then it will instead decrease the rate of the reaction. The data revealed that no additional amount of salt was the reaction that had the highest rate. As shown previously in the data table‚ the first trial’s average reaction rate of 4.5 mL/min was higher than the other two reaction rates where salt was added for trial 2 and trial3‚ 2.125 mL/min and

Factors affecting the rate of reaction between a metal and an acid The rate of a reaction can be measured by the rate at which a reactant is used up‚ or the rate at which a product is formed. The temperature‚ concentration‚ pressure of reacting gases‚ surface area of reacting solids‚ and the use of catalysts‚ are all factors which affect the rate of a reaction. Individual properties of substances also affect reaction rates. The scope of these properties is broad and there are few generalizations

Kinetics‚ A Clock Reaction Abstract The purpose for the experiment Chemical Kinetics‚ a clock reaction is to figure out the reaction rate of a solution regarding its concentration‚ temperature‚ and also determine the effects of when a catalyst is present. The experiment resulted that the concentration‚ as well as its temperature can affect the rate constant inversely the outcome of the rate constant. By conducting the experiment‚ it is also discovered that the rate order of the reaction resulted as

HOW FAST ARE CHEMICAL REACTIONS? THEORY The study of reaction rates‚ how fast or how slow a reaction takes place‚ is known as chemical kinetics. The rate of chemical reactions varies greatly. Some reactions‚ such as the explosion of an atom bomb are uncontrollable. Reactions like the decay of radioactive carbon (14C) are so slow that it takes centuries to see any noticeable change. Between the two extremes are reactions that can be measured in the laboratory. There are several factors that
