As mentioned in the text, the viscosity of liquids decreases with increasing temperature. The empirical equation η (T) = Ae^E/RTprovides the relationship between viscosity and temperature for a liquid. In this equation, A and E are constants, with E being referred to as the activation energy for flow.

a. How can one use the equation provided to determine A and E given a series of viscosity versus temperature measurements?

b. Use your answer in part (a) to determine A and E for liquid benzene given the following data:
