Adding a catalyst on a Maxwell–Boltzmann diagram is shown by:
- A
Shifting the curve to higher KE
- B
Doubling Ea
- C
Increasing the y-axis at low KE
- Dcheck_circle
Shifting Ea to a lower value (more molecules above it)
Explanation
Catalysts lower Ea, so a larger fraction of molecules has KE ≥ Ea even at the same temperature.
