Chemical Kinetics

Question

Consider an endothermic reaction, X → Y with the activation energies Eb and Ef for the backward and forward reactions, respectively. In general

  • Eb < Ef

  • Eb > EfEb > Ef

  • Eb = Ef

  • There is no definite relation between Eb and Ef

Answer

A.

Eb < Ef

∆H = Ef – Eb
For ∆H = Positive, Eb < Ef
