Which mechanism causes product yield decline when pressure exceeds optimal in Haber-Bosch reactor?

A)Le Chatelier's principle shifts equilibrium
B)Ostwald ripening causes catalyst decay
C)Arrhenius equation slows kinetics
D)Erying's theory decreases transition rate

💡 Explanation

High pressure favors reverse reaction due to Le Chatelier's principle, because reaction quotient exceeds the equilibrium constant; therefore yield declines above optimum pressure rather than kinetics slowing down given exothermic nature.
