🧠 Arrhenius Encodes Both Trends —  Falls with ,  Rises with

The Arrhenius equation is . Two of its consequences:

1.  vs  at fixed : as  rises, the exponent  becomes more negative, so  drops exponentially. The shape is a decaying exponential.
2.  vs  at fixed : as  rises, the exponent  becomes less negative, so  rises exponentially. The shape is a rising exponential.

Both plots in the question (I and II) show exactly these shapes, so both should be correct.

First move: classify Plot I and P
