use,
lnK2/K1 = (Ea/R)*{1/T1 - 1/T2}
ln(1.67/11.59) = (Ea/8.314)*{1/1125 - 1/1053}
ln0.144 = (Ea/8.314)*{8.89 - 9.50}*10^-4
-1.94 = (Ea/8.314)*(-0.61*10^-4)
Ea = (264*10^3)J/mol
= 264 KJ/mol
use, 4th data
lnk = lnA - Ea/(R*T)
ln0.0011 = lnA - (264*10^3)/(8.314*838)
-6.8 = lnA - 37.9
lnA = 31.1
A = (3.2*10^13) L/mol.s

Chemistry class:
- Please use 273.15 when converting between Kelvin and Celsius
temperatures.
- Use 96485 for Faraday Constant
- In problems that require fitting of a curve or straight line
use linear regression. Do not use trend line. Sometimes the results
can be different.
