I will confine the answer to a 1st order reaction.
Suppose we have:
For a 1st order reaction we have:
Where k is the rate constant.

See if you can measure the gradient yourself to give you -k.
If you read off the intercept i.e the point where the graph cuts the y axis, this will give you the value of
You can get
