Unformatted text preview: 6.16E-07 Since the points of the first order graphs make straight lines, the rate law is of first order. 0.2 M: rate= 0.0154[NaOH] 0.1 M: rate=0.0135[NaOH] The rate law is useful in predicting the rate based on the concentration of vice-versa. 4. Description of the Reaction The data collected by the computer shows the relationship of Absorbance and Time in the second part of the reaction. When the 0.2 M solution was added to the cuvet of crystal violet, the color changed over time, which is how the absorbance changed over time. Using the correlation coefficient calculated in the first part of the experiment, the absorbencies were translated into concentration values, so the rate late could be determined....
