Use equations:
(Eq. 12.7) Dtube =kTtube
(Eq. 12.9)
Arrhenius Equation:
12.3) Suppose that the reptation time for a polymer chain is tL=104s at a temperature of T=300K. When the temperature is increased to T=360K, the reptation time reduces to 100s. (a) What is the activation barrier for the tube diffusivity process over this range of temperatures? (b) Suppose that the length of the polymer chain is doubled. What is the reptation time at T=320KStep by Step Solution
