Introduction The reaction rate of a chemical reaction is determined as the change in the concentration of a reactant or product over the change in time. [1] The rate of a reaction is determined by experiment. Many factors influence the rate of a reaction: the nature of the reaction‚ concentration‚ pressure‚ temperature‚ and surface area‚ presence of catalyst and intensity of light. [2] For a chemical reaction‚ the rate law or rate equation is a mathematical expressed equation that links the reaction

good and the bad that era represents. The Great Depression‚ for example‚ opened with a stock market crash on October 29‚ 1929‚ which troubled the U.S. economy. It was so impactful in the 1930’s that anyone that grew up during this time struggled. Harper Lee‚ an American author‚ was born in 1926 when the government was following the Laissez-faire approach (“Causes of the”). She started writing to tell her own story‚ and several of

Lab Report Experiment #3 Chemical Aspects of Life The objective of the Reducing Sugar Test was to test if the substance has a reducing sugar in it by adding Benedict’s solution and heating it‚ there would be a color change if a reducing sugar is present‚ or it will remain blue (no reducing sugar). The objective of the Starch test was to test for starch in substances by using Iodine. The iodine will cause a substance to turn to a dark blue color if it is positive for starch. The objective for

This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures of compounds’ (Wikipedia‚ 2011). This method is similar to thin layer chromatography‚ but the compounds in the mixture are collected separately. Green dye is used in this experiment that consists of blue and yellow constituents
