| Enter time and
concentration data in the text area. Data will be
plotted along with a linear least-squares
fit. To see the differences
between different orders, try plotting C
vs time, ln C vs time, and 1/C vs time
for each set of data below.

The straight line can be
adjusted manually by dragging it around:
positioning the cursor toward either end
of the line while allow that end to move
while positioning the cursor toward the
middle moves the whole line up and down. |
Exercise.
These sets of kinetic data (time, concentration)
can be copied (one set at a time) and pasted into
the data area. In each case the concentration of
the reactant being monitored is decreasing as the
time of reaction progresses. Which set is zeroth
order in the reactant being monitored? Which is
first order? Which is second?
