← ScienceWhich outcome follows increased reactor by-product concentration, limiting conversion?
A)Equilibrium shifts favoring reverse reaction✓
B)Activation energy barrier is lowered
C)Forward rate constant directly increases
D)Effective catalyst surface area increases
💡 Explanation
Increased product concentration changes equilibrium, following Le Chatelier's principle, because the system shifts away from product formation to relieve that stress. Therefore, the equilibrium shifts toward reactants, diminishing the forward rate, rather than affecting kinetic constants directly.
