← ScienceWhich effect accelerates free radicals at grain boundaries?
A)Increased chemical potential gradient✓
B)Reduced activation energy barrier
C)Enhanced electron excitation rate
D)Increased surface vibrational modes
💡 Explanation
Increased concentration gradients introduce a higher chemical potential, driving diffusion. This flux promotes accelerated transport along regions of grain boundary curvature. Radicals accumulate there because chemical potential differences are higher, therefore diffusion increases rather than kinetic changes being enhanced.
