Question

For a set of parallel first-order decomposition paths $A \rightarrow B$ ($k_1$, activation energy $E_{a1}$) and $A \rightarrow C$ ($k_2$, activation energy $E_{a2}$), the overall effective activation energy $E_{a(eff)}$ for the destruction of A is rigorously expressed by which Arrhenius derivation?

Prashant Kotian · Accepted Answer

Correct answer: B. Taking the Arrhenius derivative of the sum of the composite overall rate constant mathematically generates a weighted average of the activation energies, explicitly defined as .
