2. A gel-time test on an epoxy resulted in the following data: Time (min) T (C) 140 4 130 7.5 120 14 110 25 105 34.3 (a) Plot In(gel time) versus 1/7 (where T is the temperature in K). (b) Assume that gel time can be represented by Arrhenius equation: Egel = A exp E RT where E = activation energy, R = universal gas constant, and A = constant. Determine the values of A and E. (c) Determine the gel time at 100 and 150 C using the Arrhenius equation.
