Oxidation of Alcohol In this experiment the absorbance rate of chromic acid was found using a spectrometer. The chromic acid was used in an aqueous solution with ethanol represented by 6H 3 O+ 3CH 3 CH 2 OH (aq) +2H 2 CrO 4 3CH 3 CHO (aq) + 2Cr 3+ (aq) +14H 2 O (l) . Using the formula ln((A0-Ai)/ (A-Ai))=kt the a graph of absorption vs. time was created, represented by y=0.009x-.033. The k value is also the slope of the line, which is .009.

Unformatted text preview: It represents the rate of absorption until the reaction runs to completion. Also, the half life of the reaction is 77.01 seconds. There is error in the calculations because the rate law is pseudo first order because the ethanol used was ignored. Relative to the chromic acid the ethanol hardly changed because so much was used compared to the chromic acid....
