Bonds form on energetic A+A crashes, break on hard knocks — watch fwd and rev converge.
Temperature moves the equilibrium itself (van ’t Hoff), not just the pace — and the equilibrium clock restarts with every move.
With the catalyst, collisions must carry 100 kJ/mol to bond.
Forming the bond releases ΔH — so breaking it needs Ea + ΔH = 135 kJ/mol. Exothermic forward.
Push a settled vessel off balance and watch the rates answer — the forward rate jumps on a pour of A; the vessel replaces what you pump out.
Vessel paused. Start it and collisions do the rest — energetic A+A crashes bond, hard knocks break dimers, and the balance emerges on its own.
