If you have a graph of LN concentration on the Y axis and Time on the X axis, graphing the data gives you a Y=Mx+B, how would you use this to find the rate constant.

Finding rate constant using a graph?

If this is a 1st order reaction (& if ln C vs t is a st line it is), the equation forconcentration as a fn of time is:

C(t)=C0*e^(-rt) or

ln (C(t))=ln(C0)-rt

the slope of the st line is the negative of rate constant: m=-r

M (the slope) is your rate constant.
