What does “Activation energy” actually mean in Chemical Kinetics, and why does it matter for NEET?
the minimum energy barrier reactants must cross; a catalyst lowers it.
In simple words: the minimum energy barrier reactants must cross; a catalyst lowers it. Getting Activation energy clear matters because NEET questions on Chemical Kinetics usually test this idea directly, not just a formula you memorised.
Key point
Activation energy
Common mistake
thinking a catalyst changes ΔH or the position of equilibrium.
Memory tip
a catalyst speeds BOTH directions equally — it never shifts equilibrium.
