We’re being asked to determine the frequency factor (A) of a reaction 


We’re given the following data

 Temperature (K) 

 Rate Constant (1/s)

800

3.24 x 10 - 5

900

0.00214

1000

0.0614

1100

0.955


We will plot it using the following two-point form of the Arrhenius Equation:


ln k=-EaR 1T + ln A


where: 

k = rate constant

Ea = activation energy (in J/mol)

R = gas constant (8.314 J/mol • K)

T = temperature (in K)

A = Arrhenius constant or frequency factor
