what was the reaction rate (change in absorbance per minute) for the medium enzyme concentration? remember, you have no data recorded for time zero, so that is not a data point to include in your calculations. note, you subtract your final reading from your initial reading (time zero is not a data point). and divide by the time that transpired between initial reading and final reading. effect of enzyme concentration on reaction rate:time, secondslow enzymemedium enzymehigh enzyme000030.008.015.01960.012.022.02690.017.026.034120.020.031.039
