Chem 1310: Introduction to physical chemistry Part 2: exercise 55, p662 Reaction of p-methylphenyl acetate with imidazole

Show the raw data T(°C)k (L mol -1 s -1 ) E E E E E E-01

Prepare data for the Arrhenius plot 1/T (K -1 )T(K)T(°C)k (L mol -1 s -1 )ln k E E E E E E

Extract the data 1/T (K -1 )T(K)T(°C)k (L mol -1 s -1 )ln k E E E E E E slope = (K) R = J mol -1 K -1 E a = -R*slope = 28.6 kJ/mol intercept = 8.39 A = e intercept = 4400 (L mol -1 s -1 ) Predict rate at 100°C: rate = 4400*e /(8.314*373.15) = 0.43 L mol-1s-1

Extrapolation, very sensitive to errors! 1/T (K -1 )T(K)T(°C)k (L mol -1 s -1 )ln k E E E E E E slope = (K) R = J mol -1 K -1 E a = -R*slope = 26.8 kJ/mol (was 28.6) intercept = 8.39 A = e intercept = 2070 L mol -1 s -1 (was 4400)
