If the frequency factor is 1.2*10^13/s , what is the activation
barrier?

The rate constant of a reaction at 33 Degrees Celsius was measured to be 5.8×10^-2 /s.

The rate constant of a reaction at 33 Degrees Celsius was measured to be 5.8×10^-2 /s.

## Answer

k = A·e^{ -Ea/(R·T) }

<=>

ln(k/A) = -Ea/(R·T)

<=>

Ea = -R·T·ln(k/A)

= - 8.314472Jmol?¹K?¹ · (33 + 273.15)K · ln(5.8×10?²s?¹/
1.2×10¹³s?¹)

= 83907Jmol?¹

= 83.91kJmol?¹
