Unformatted text preview: reagent. This error would cause the reaction rate to be calculated incorrectly as the reaction would not happen at the rate accepted. This lab introduced students to the concepts of spectrophotometers and determining rate laws and constants. Both of these are important to the concepts learned in class. The graph of [Cr 3+ ] t Vs t was the nearest to a straight line, therefore the rate law was of the zero order. The average value of k was 2.25x10-5 7.5x10-6 . These two calculated values allow a rate law of rate = 2.25x10-5 [Cr 3+ ] 1 .
