Title: How do you find the scale of a graph on a exam when its points are given?
Post by: AussieKenDoll on August 13, 2020, 01:46:25 AM
See the attached photo
It shows the points for Temperature and Kp values to plot lnkp = -H/RT graph
How could I easily and quickly determine what is the best scale to draw the graph on a graphing paper at exam?
We are given this kind of questions anyway!
Is there an easy method?

Well you're not going to plot K versus T. So the first thing I'd do is convert those into the values you will actually plot, which should inform what scale you should be plotting over.

Always try to make the graph as large as possible, so use just a little below and above the limits of the data
