← ScienceWhich outcome occurs when catalyst surface area exposure lessens in a fixed volume reactor?
A)Equilibrium constant remains unchanged✓
B)Reaction order changes dramatically
C)Activation energy decreases greatly
D)Pressure within the reactor increases
💡 Explanation
The equilibrium constant remains unchanged because it depends on thermodynamic properties which do not vary with surface area; the reaction rate does change, therefore the equilibrium constant remains constant, rather than other kinetic parameters being impacted.
