Determining Activation Energy

[laurence14b2f]

Hey folks! How do we experimentally determine the activation energy of a reaction using the Arrhenius equation, and what are the potential sources of error in these experiments? Thank youuuu!

To experimentally determine the activation energy (Ea) using the Arrhenius equation, you need to measure the rate constants (k) of the reaction at different temperatures and then plot a graph of ln k versus 1/T. The slope of this graph is equal to -Ea/R, allowing you to calculate the activation energy.

Potential errors can come from not maintaining accurate temperature control and reaction impurities.
