← ScienceWhich irreversible consequence arises when an endothermic chemical reaction is repeatedly driven within a closed oscillating chemical reactor?
A)Increased amplitude of temperature oscillations
B)Decreased rate of net product formation✓
C)Reduction in overall reaction enthalpy
D)Diminished activation energy requirements
💡 Explanation
The repeated reaction causes decreased product formation because entropy accumulates due chemical kinetic hysteresis. Therefore, the chemical system loses efficiency over each reactive cycle, rather than enhancing temperature variations or reducing activation energy because product selectivity suffers, thereby bypassing preferred reactive paths.
