← ScienceWhich consequence results when a packed-bed reactor's feed flow rate is increased sharply without adjusting temperature?
A)Reaction equilibrium shifts exothermically
B)Reaction equilibrium remains unchanged✓
C)Reaction equilibrium shifts endothermically
D)Catalyst surface area decreases rapidly
💡 Explanation
Conversion decreases because residence time is reduced. The reaction equilibrium depends primarily on temperature therefore, a significant flow increase won't shift the equilibrium, rather than composition-related effects dominating, when temperature constraints exist across parameters in place within catalytic beds.
