the verdict
SUPPORTED
the evidence backs this
confidence 83/100
Physical chemistry and materials science literature consistently demonstrate that the pre-exponential factor in the Arrhenius equation can exhibit temperature dependence, often manifesting through compensation effects or complex multi-step reaction kinetics.
