Goals of this lab:
•
Create and use a calibration curve for the absorbance/concentration relationship for crystal violet
•
Evaluate absorbance versus time measurements to determine the order of a reaction
•
Analyze graphs of data to determine best linear fit
•
Calculate rate constants from best-fit lines and values
•
Assemble a complete kinetic description of the reaction from data gathered
Your lab report will be grade on the following criteria using a poor/good/excellent rating system (see the Self
