2 Kinetics Can you: cut clashing theory in terms of strike frequency, conflict energy, activation energy and the constituent of successful collisions Outline an experimental procedure for measuring the rate of a reaction which involves a gas being evolved plan graphs to show how the concentration of a reactant varies with time in a chemical reaction and have it off that the gradient of the graph is the rate of the reaction Sketch the Maxwell-Boltzmann distribution of molecular energies at two temperatures apologise the greathearted effect on rate of reaction of a clear increase in temperature by reference to Maxwell-Boltzman, collision energy, fraction of successful collisions and collision frequency Define the term accelerator pedal and explain that the catalyst lowe rs the activation energy by providing an al! ternative reaction pathway Explain by reference to Maxwell-Boltzmann how a catalyst increases the rate of a reaction Explain how concentration, obligate and particle size affect the rate of a reaction Topic 2.3 Equilibria Can you: Explain the term dynamic vestibular sense and recall that all equilibria are dynamic...If you want to get a full essay, order it on our website: OrderEssay.net
