Remember that old equation k = Ae^(-Ea/RT)?
For some reason when I have both my rate and exponential factor, the frequency factor solved algebraically comes out different from the way the
textbook tells me to do it. The textbook says to just draw a straight line from the points I plotted from the data until it hits the y-axis. That
point on the Y-axis is my frequency factor. Anyone know why this is? There are no errors in my calculations...

did you linearise by taking natural logs on both sides?

No. I don't remember that partcular equation. But I recall many like it. Arrhenius equattions they are called.
Assuming that T is your independent variable, you linearise by plotting log(k) against 1/T.
That should do exactly what you want.
