What effect do acids and bases of varying PH levels have on the efficiency of catalase? Catalysts are an extremely important part of the experiment, but to understand catalyst you first must understand Activation energy. Activation Energy is “the minimum amount of energy that is required to activate atoms or molecules to a condition in which they can undergo chemical transformation or physical transport.” (Encyclopedia Britannica, "activation energy | chemistry"). A Catalyst is “is a substance which speeds up a reaction, but is chemically unchanged at the end of the reaction. When the reaction has finished, you would have exactly the same mass of catalyst as you had at the beginning.” A catalyst provides an “alternate route” for a reaction, one which has lower activation energy, there for speeding up the reaction by requiring the reaction to need less energy to begin, but only in specific conditions will they work to their full potential. (Clark, "The effect of catalysts on rates of reaction") An enzyme is a “catalyst in living organisms, regulating the rate at which chemical reactions proceed without it being altered in the process”. Catalysts work optimally in certain PHs, and can be altered when in temperatures and PH levels that are different then what they are used to (http://www.britannica.com/science/enzyme). Acids and bases are both materials that can inhibit the efficiency of a catalyst in a reaction. Materials can be considered acids or bases depending on their…
