🧠  vs  — Slope Gives Forward Activation Energy or Enthalpy

For Arrhenius (if  is rate constant): slope , giving .

For van't Hoff (if  is equilibrium constant): slope , giving .

Both are linear plots with negative slope for exothermic.

First move: identify whether  is rate or equilibrium; read slope.
