Which outcome limits performance when reactor temperature increases?

A)Equilibrium constant shifts unfavorably
B)Catalyst surface area increases reactivity
C)Residence time distribution becomes uniform
D)Kinetic rate constant always accelerates

💡 Explanation

An unfavorable equilibrium constant shift occurs, because as temperature rises, the equilibrium shifts towards either reactants or products depending on reaction enthalpy; therefore product formation is reduced, rather than reactions speeding up.
