Plot a Graph and Determine the Rate: Make a graphical plot of reaction time (x-axis) and spectrophotometer readings [Use the calculated average] (y-axis). Determine the initial velocity (rate) of the reaction by extending the initial straight-line portion of your reaction curve and calculating the gradient of the straight line (difference in y/ difference in ×). The units of the rate will be in absorbance units min' (abs min-"). What is the rate of the reaction based on your plotted values:

Plot a Graph and Determine the Rate:

Make a graphical plot of reaction time (x-axis) and spectrophotometer readings [Use the calculated average] (y-axis).

Determine the initial velocity (rate) of the reaction by extending the initial straight-line portion of your reaction curve and calculating the gradient of the straight line (difference in y/ difference in ×). The units of the rate will be in absorbance units min' (abs min-").
