The Hill Every Reaction Has to Climb

You'll learnto read the barrier, the activation energy and the enthalpy change off one energy profile.

The products end up lower than the reactants, so why does a wildly exothermic reaction sit on your desk for years doing nothing? One curve answers it. Twelve short steps; press Next for each one.

12 STEPS · 6 QUICK CHECKS · Ea = 60 kJ · ΔH = −15 kJ · v4

one curve · the climb, the finish, and the climb back
Before you start
What you're looking at
Potential energy up, reaction progress across, and two flat shelves with the middle of the path missing.
The question
The products end up lower. What shape does the path between them take?
