Answer 1

R = R_0 e^- E/RT a) rate constant at 100 degree c R = 1.3 times 10^13 e^- 35 times 10^3/1.987 times 373 R = 1.987 cal/mol - k R = 4.03 times 10^- 8 s^- 1 b) - r_A = R p_A/RT = 4.03 times 10^- 8 times 1/0.082 times 373 = 1.318 times 10^- 9 mol/Ls c) ln R = ln R_0 - E/RT ln R_2/R_1 = E/R (1/T_1 - 1/T_2) ln R_2/R_1 = 35 times 10^3/1.987 times (1/100 - 1/120) = 29.36 R_2/R_1 = 5.634 times 10^12 r_2/r_1 = R_2/R_1 = 5.634 times 10^12
