✓ Correct
The first-order rate constant () is equal to the negative of the slope produced by plotting the natural log of the concentration over time. In order to find the slope of the plot, the natural log of each
concentration must first be calculated.
Part C
These natural log values can then be used to plot a trend line, which will have a slope of -3.67 x 10-³. Since it is the negative of the slope, the value of ke will be 3.67 x 10-³ min-¹.
[sucrose 39 =
Using the rate constant found in Part B, calculate the concentration of sucrose at 39 min if the initial sucrose concentration were 0.316 M and the reaction were zero order in sucrose.
