a. Enter data as shown
b.Selectedqrea in blue
Exp. 5, Part B
c. Chart Wizard will generate this graph (I also used a trendline for each set of points ).
Step 1
Reaction rates
Step 2
a. Pick two points on the 0.5mM line
I chose these two points
b. Record the x and y values for each point
Here, X2= 15 min X1= 5 min Y2= 0.4 units Y1= 0.23 units
Y2, X2
Y1, X1
c. Calculate slope of line
= (Y2 – Y1)/ X2 –X1)
=(0.4-0.23)/ 15-5)
=0.17/10min or 0.017units/min
d. Now do the same to calculate the slope for every other line.
Step 3
a. Enter slope of each line on a tableIn Chart Wizard, highlight blue area and select XY scatter and this style to make a graph.
Note that the rate for 2.5 mM substrate is unexpected . Even so, conclusions can be made about the overall effect of substrate concentration on reaction rates.
