Homework Statement
Given for polystyrene K = 1.6x10^5 and a = 0.71
and for PVC K = 1.5x10^5 and a = 0.77
a universal calibration curve has been created from PS and the molar mass of PVC at a certain elution volume has been calculated.
The part I'm not sure on is the question:
Show which of...
As far as I can see what has been done is that given that T1/T2 = e^u0 then T1/e^u0 = T2.
Knowing that T1 is tightside tension and therefore Tmax, how is it that T1 = 1 in order to rearrange for T2 = e^u0?
I'm sure the answer is very obvious but I really can't see what is going on.

I do no understand as shown in the above picture why T1 = 1 to make e^u0 = e^-u0, could anyone offer an explanation as to why this is the case?
Thanks
