Math 251: The Annihilator Method: Using higher order homogeneous equations to solve non-homogeneous equations The annihilator method is a fast method for solving certain non-homogeneous differential equations. A variation of this method is sometimes called the “method of judicious guessing” or the “method of undetermined coefficients.” In each variation‚ the work that must be done is the same; the difference is only in the background understanding of why the work is being done. The key idea of the

Since most reactions occur under constant atmospheric pressure‚ the heat of a reaction is equal to ΔH‚ which is generally reported in units of kilojoules (kJ) per mole of the reactants and products as shown in the balanced thermochemical equation. For example‚ the reaction between hydrogen gas and oxygen gas to

OCl (aq) + H2O (l) + 2e → Cl (aq) + 2OH (aq) Our goal in this experiment was to observe the reaction and concentration changes between Allura Red and bleach and determine the rate law for the reaction. The rate of reaction can be found by the equation rate = ∆concentration / ∆time = k[Allura Red]x[NaOCl]y The x and y values indicate the order with respect to each reactant‚ and k represents the rate constant for the reaction. These values had to be determined experimentally. In order to determine the rate law of the reaction
Premium Rate equation Chemical kinetics
The rate of a chemical reaction is the measure of change in concentration of the reactants of the change in concentration of the products per time. The rate of a chemical reaction is influenced by the concentration of the reactants‚ temperature‚ and the presence or absence of a catalyst. Through finding the time and concentrations of the reactants‚ it is possible to find the rate of reaction and k. To perform this experiment‚ you need two erlenmeyer flasks‚a timer‚ a LabQuest with a temperature

A sodium hypochlorite (NaOCl) solution was also prepared by mixing 8.00 mL of a stock solution with DI water to obtain 50 mL. The concentration of the NaOCl solution was also determined using the following equation: M1V1 = M2V2 (Eq. 2) The second part of the experiment involved mixing different proportions of both the NaOCl solution and blue food coloring solution‚ and this was performed in order to determine the proportion of each which was necessary to
