Science

Which outcome occurs when pressure increases isochemically in a Vanadium Pentoxide catalyst bed reactor?

A)Equilibrium shifts toward lower volume.
B)Activation energy barrier increases quickly.
C)Catalyst surface area rapidly diminishes.
D)Reaction rate constant declines sharply.

💡 Explanation

Equilibrium favors decreased volume via Le Chatelier's principle because increased pressure causes the system to minimize the added stress; therefore, reactants reduce in volume, rather than a change in activation energy, as the catalyst remains the same.
