I keep getting “Rate constant” questions wrong in Chemical Kinetics. What's the trap?
thinking k depends on concentration.
The usual trap: thinking k depends on concentration. How to avoid it: k depends on temperature and catalyst, not on how much reactant you have. Go back to the definition — the proportionality constant k in the rate law; it rises sharply with temperature.

Common mistake
thinking k depends on concentration.
Memory tip
k depends on temperature and catalyst, not on how much reactant you have.
