1. The irreversible isomerization reaction, A + B, was carried out in a batch reactor at 250C and 1 atm. The following concentration versus time data were obtained. Time 0 2 4 6 8 10 12 14 16 18 20 (min) CA 20.00 18.02 16.24 14.64 13.19 11.89 10.72 9.66 8.70 7.84 7.07 (mol/L) Determine the reaction order and specific reaction rate by using a) Differential (numerical) method b) Integral method c) This reaction was also performed at 300C and 1 atm with same initial concentration. After 10 minutes, 75% of A isomerize to B. What is activation energy of the reaction
