Chemical 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

Title: Kinetics: The Rate of a Chemical Reaction Objectives: 1. To study the kinetics of chemical reaction‚ 2 I- + S2 O82- I2 + 2 SO42- . 2. To study the effects of reactant concentration (persulphate‚ S2O82-‚ and iodide‚ I-) and temperature on the rate of chemical reactions. ( i) Study the effect of 0.20M (S2O82-) on the rate of chemical reaction. ( ii) Study the effect of 0.10M (S2O82-) on the rate of chemical reaction. ( iii) Study the effect
Premium Chemical reaction Reaction rate Rate equation
Introduction Chemical Kinetics‚ described as the study of rate of chemical processes‚ varies on many factors to determine the time needed for a reaction to complete. The rate of reaction of a chemical reaction is important‚ as reactions are of little use if the time period needed for the reaction to occur is too lengthy. Many factors influence the rate of a chemical reaction‚ such as temperature‚ concentration and surface area. The order of the reaction is based on the concentration of the reactants

What Factors Affect Chemical Equilibrium? Introduction: In investigation 14‚ “What Factors Affect Chemical Equilibrium?”‚ the purpose was to find out which reagents caused a change in the chemical equilibrium. A deep red color was formed when Iron Nitrate [Fe(NO3)3 (aq)] was mixed with water and Ammonium Thiocyanate [NH4NCS (aq)]. The product of these two reactants was Iron Thiocyanate(FeNCS). After different trials of mixing the given reagents

The history of the periodic table reflects over a century of growth in the understanding of chemical properties‚ and culminates with the publication of the first actual periodic table by Dmitri Mendeleev in 1869.[1] While Mendeleev built upon earlier discoveries by such scientists as Antoine-Laurent de Lavoisier and Stanislao Cannizzaro‚ the Russian scientist is generally given sole credit for development of the actualperiodic table itself. The table itself is a visual representation of the periodic

Pharmacognosy is the study of drugs of natural origin. The term comes from two Greek words: "pharmakon" meaning drug or medicine‚ and "gnosis" meaning knowledge. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical‚ chemical‚ biochemical and biological properties of drugs‚ drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources". Plant preparations are said to be medicinal or herbal when they
