Plotting Natural Log of Concentration versus Time
« on: July 26, 2007, 04:46:59 PM »
Hi All,

How do I calculate the natural log of concentration vs time?  Do I simply press "ln" on the calulator followed by the concentration to obtain the natural log or do i have to use something like:

ln[A] = -kt +ln [A] sub o

mind u, i dont know the k, but i do know conc of the product and time...

you can use normal graph axes and plot the ln-values of [A] against the time

the result will be a linear curve with the interception on the y-axis = ln[A]0 or [A]0 with slope = -k
