Why is coefficient of static friction greater than coefficient of kinetic friction even though kinetic friction force is greater than static friction force?

Explanation:
Static friction is the force that keeps a stationary object in place.
In most applications, static friction is caused by both adhesion and abrasion of the contacting surfaces.
Overcoming the static friction between two surfaces essentially removes both the molecular obstacles.
With most of the adhesion and abrasion being overcome to induce movement, the resistance to motion between the surfaces is reduced.
Thus, the coefficient of kinetic friction is lower than that of static friction.
