1) ln (K1 / K2) =Ea / R [1/T2 -
1/T1]
K1= 2.5*10-3 sec-1 ; T1
= 332 K
K2 = ? ; T2 = 375 K
Ea = 1*105 J/mol ; R = 8.314 J/mol K
ln (2.5*10-3 / K2) =1*105 / 8.314
[1/375 - 1/332]
ln (2.5*10-3 / K2) = -4.154216
2.5*10-3 / K2 = e-4.154216 =
0.015698
K2 = 0.15925 sec-1
2) T1 = 332 K ; K1 = 0.15925
sec-1
T2 = ? ; K2 = 2*0.15925 = 0.3185
sec-1
use the same formula
ln (0.15925 / 0.3185) = 1*105 / 8.314 [1/T2 -
1/332]
-5.7628*10-5 = 1/T2 - 1/332
T2 = 338.4759 ~ 338.5 K
