Discuss the effect on the rate of reaction due to concentration increases of reactants. From graphs show how the rate is directly proportional to the concentration of reactant increases. Use the example of highly concentrated hydrogen peroxide which becomes violently explosive and decomposes at a rate which is too rapid to measure. Discuss why this is due to collision theory. Determine that the rate of decomposition can be shown by the formula rate=k(concentration). Show a graph plot. Analyze a second concentration v rate reaction
