    The Activation Energy of Bromide ion and Bromate ion To Determine the Activation Energy of the Reaction between Bromide ion and Bromate (V) ion in Acid Solution Objectives: By reacting Potassium Bromide and Potassium Bromate in the acid solution in varies temperature, we can then determine the Activation Energy of the reaction in different temperature through the equation:[IMAGE]. Questions: 1. Give an equation for the reaction between phenol and bromine. 2. What is the use

  • The Activation Energy for the Molecule of HALS Reaction using GAUSSIAN 09 via the WebMO Interface

    877 Words  | 4 Pages

    the energy between two cases of that compound by 119 kJ/mole with basis set 6-311+G(d,p) and 128 kJ/mole with basis set 6-31 G(d) and similarly in level of theory(B3LYP). Therefore, the protonated nitrogen of the HALS molecule had higher energy than the neutral nitrogen through the potential energy of the reaction. Accordingly, the hypothesis that was reported becomes incorrect against to the calculation result found it from Gaussian program. 4.2 The aim of calculation the activation energy The

    of collision theory, then it will discuss on Activation Energy. After that, activation complex will be explained using enthalpy diagram and catalyst pathway will be focused. Following this, there will be a describing about homogeneous and heterogeneous catalysts, also their own mechanisms and examples. Lastly, this essay will represent the catalytically poisoning. Discussion The Maxwell-Boltzmann Distribution According to Webchem(2005) the Kinetic energy of atoms and molecules can be found using formula

  • Temperature's Affect on Chemical Reactions

    1235 Words  | 5 Pages

    When exposed to temperature change, the activation energy of a reaction can be met much more quickly (or slowly) than it would have been. As the temperature goes up, the rate of reaction increases. Temperature is a very flexible contributor to the rate of reactions and chemical reactions in general. Changes in temperature can affect almost all parts of a reaction, such as the kinetic energy of the molecules, the speed of enzymes, and how quickly activation energy is met. While temperature changes many

  • Analysis Of Sodium Hydroxide And Crystal Violet

    800 Words  | 4 Pages

    Discussion Objectives: This experiment is monitoring the reaction of sodium hydroxide and crystal violet using spectroscopy. Graphical methods will be used to determine the kinetic rate law, rate constant and activation energy for the reaction. General Discussion: The order of hydroxide was determined by the varying the initial concentration of hydroxide in runs 1 and 2. We used the isolation method, which calls for having much higher concentrations of one reactant then the other, in this case

    are strong and hard to break under room temperature; I believe that this may have an impact on the solubility of KNO3 at low temperatures, where there is very little energy present to break these bonds. Particles move faster and collide with a greater energy output. A greater proportion of these particles now have enough energy to react. Therefore there is a greater chance of a collision between KNO3 and water molecules resulting in a successful reaction. Hypothesis My hypothesis is

  • Investigation of the Rate of Reaction

    676 Words  | 3 Pages

    The particles in a gas undergo random collisions in which energy is transferred between the colliding particles. Prediction: I predict as the concentration is changed the rate of reaction will increase. When the concentration is changed the particles will have more energy and therefore move faster. Therefore they will collide more often and with more energy. Particles with more energy are more likely to overcome the activation energy barrier to reaction and therefore react successfully. If

  • Sodium Thiosulphate and Hydrochloric Acid Reaction Investigation

    1390 Words  | 6 Pages

    reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called the activation energy, or Ea. The size of this activation energy is different for different reactions. If the frequency of collisions is increased the rate of reaction will increase. However
