Which factor does NOT affect the rate constant k of a reaction?
A.Initial concentration of reactants
B.Temperature
C.Activation energy
D.The presence of a catalyst
Explanation
Core Concept
k is concentration-independent — concentrations affect the rate through the rate law, not through k. Temperature and activation energy (via catalyst) change k.
Correct Answer
AInitial concentration of reactants
