2 Kinetics Can you: beg off clashing theory in terms of strike frequency, impact energy, activation energy and the ingredient of self-made collisions Outline an experimental procedure for measuring the rate of a reaction which involves a gas being evolved resume interprets 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 statistical distribution of molecular energies at cardinal temperatures apologise the large offspring on rate of reaction of a sm tout ensemble summation in temperature by name and address to Maxwell-Boltzman, collision energy, fraction of successful collisions and collision frequency Define the term gas pedal and explain that the catalyst lowers the activation energy by providing an alternative reaction pathway rationalise by reference to Maxwell-Boltzmann how a catalyst increases the rate of a reaction Explain how concentration, pressure and component size affect the rate of a reaction Topic 2.3 Equilibria Can you: Explain the term high-power equipoise and recall that all equilibria are dynamic...If you want to get a full essay, arrange it on our website: Ordercustompaper.com
