2 Kinetics Can you: explain clashing theory in terms of strike frequency, opposition energy, activation energy and the fraction 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 capacious effect on rate of reaction of a weakened increase in temperature by reference to Maxwell-Boltzman, collision energy, fraction of successful collisions and collision frequ ency Define the term gas and explain tha! t the catalyst lowers the activation energy by providing an option reaction pathway Explain by reference to Maxwell-Boltzmann how a catalyst increases the rate of a reaction Explain how concentration, twitch and particle size affect the rate of a reaction Topic 2.3 Equilibria Can you: Explain the term dynamic counterpoise and recall that all equilibria are dynamic...If you want to get a full essay, order it on our website: BestEssayCheap.com
