← ScienceWhich outcome changes when inhibiting a reaction's mass-transport limited regime?
A)Observed rate constant decreases✓
B)Equilibrium constant rises quickly
C)Activation energy becomes elevated
D)Gibbs free energy shifts slightly
💡 Explanation
The observed rate constant decreases if mass transport becomes limited, because reactants can't reach the active sites as efficiently. This is due to mass transport being a limiting factor, therefore the observed rate constant drops rather than being thermodynamically limited or affected.
