Kinetic data and their interpretation - Interpretation of rate constants
3 important questions on Kinetic data and their interpretation - Interpretation of rate constants
What are useful parameters to elucidate reaction mechanisms?
Activation energy and Gibbs free energy. Both yield a relation between rate constant, energy difference and reaction temperature.
What is the Arrhenius equation?
k(obs) = A * exp (-Ea/(RT))
How can Ea be determined?
By measuring the rate constant at two different temperatures.
k1/k2 = exp (-Ea/R (1/T1 - 1/T2))
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
