Reaction rate

(EEI) investigated the effect in which concentration had on the rate of reaction. The purpose of this experiment is to test different concentrations of hydrochloric acid with sodium thiosulfate and to see how long it would take until the cross underneath the flask is no longer visible through the milky white solution. Collision theory A collision is when two or more object run into each other. But collision theory is, that only some particle collisions make changes (or are fruitful). Fruitful or effective collisions require enough energy to break pre existing bonds and form new ones. In order to have enough energy the particles they need to have the right orientation and enough force.…

The rate at which a reaction occurs, referred to as reaction rate, is a type of reaction property that directly measures the extent of a reaction. Changes in concentration affect reaction rates in chemical formulas, and if the reaction is not specifically known, the rate cannot be determined. The rates are given in negative or positive measurements depending on whether the concentration is a reactant or product. Knowing this, the first step in finding the reaction rate would be to determine the…

The rate at which a reaction takes place can be affected by the temperature, the concentration, the particle size, and by using a catalyst but two that really affect the reaction are temperature and concentration of the solute and solvent. The rate of a reaction is determined by the temperature and the concentration which in this case determine how fast or slow the reaction will occur. In both cases something is being increased, for example, placing solutions A and B in the warmed water…

The Effects of Substrate Concentration and Temperature on a Catalase Reaction Rate Introduction Catalase is a vital component in the human body. The most crucial of which would be Enzymes, these are protein catalysts. A catalyst speeds up a chemical reaction rate. Virtually all chemical reactions within the human body require a catalase enzyme to be completed in the proper amount of time. The decomposition of hydrogen peroxide to oxygen and water can be completed with the catalase enzyme…

What factor(s) affect the rate of reaction? Problem: What effects does temperature have on the rate of reaction? Purpose: The aim of this investigation is to investigate how changing the temperature of sodium thiosulphate affects the rate of reaction in a chemical reaction. In order to complete this practical the temperature will be changed three times and the rate of reaction will be measured each time. Variables: Independent: -the temperature of the sodium thiosulphate. Dependent:…

18 – Reaction Rate of Notongooglenium – Angus Dally Research Question: How does the presence of a Notongooglenium oxide catalyst effect the rate of hydrogenation of ethenol (vinyl alcohol)? Aim The aim of this experiment is to find the effect of the manganese oxide catalyst, a similar compound to Notongooglenium Oxide, on the rate of hydrogenation of ethenol (vinyl alcohol). Introduction Notongooglenium Notongooglenium is a newly discovered element with an atomic number of 24.5. Due to its…

conclude that the reaction with the fastest reaction rate is magnesium and hydrochloric acid. Initially, it was hypothesized that the reaction with hydrochloric acid would have the fastest reaction rate due to its high acidity observed from the pH scale. From there, the following reactions were based on the pH of the acid involved as well as the concentration of hydrogen ions/atoms within the acid molecule. As a result, it was hypothesized that the sulfuric acid reaction would be the second…

Temperature and pH will affect enzyme function by increasing the reaction rate because as temperature increase so is the rate of reaction and extremely high or low pH will result in the denatured by decreasing the reaction rate. The function of this experiment was to investigate the influence of the concentration of enzyme on the rate of reaction. The rate of reaction in this experiment was subjected by the amount of Guaiacol, H2O2, Extracts, and Buffer (pH5). The reaction rates with different…

The addition of the succinate was required in order for the DPIP to be reduced. The addition of the succinate did impact the reactions, however too much the succinate will not be as successful because based on Table 1.4, it was shown that the Sample ID “2” had 100μL of the succinate and it had the reaction rate of 0.68 %/min. However, with the excess amount of succinate which was 200 μL with a reaction rate of 0.0533%/min. However, no addition of succinate could definitely lessen the reaction…

Kinetic can be defined as a study of the speeds or the rates of chemical reactions. The factors that could affect the rates of the reactions are physical state, reaction temperature, catalysts, pressure, concentration of solution, and reaction time. The change of the speed of the reaction can be predicted based on the different reaction conditions. Kinetic study is important because it can describe information about the reaction mechanism. The concentration has affected the frequency which the…
