A reaction force is bascally a force that acts in the opposite direction to an action force. It can better be described as when one fires a bullet from a gun, they feel being pushed backward. The action force in this case is the gun pushing out the bullet and the reaction is the bullet pushing back on the gun and its holder.
Always centrifugal is the reaction force for centripetal
The reaction force to the friction acting on the car is the friction force acting on the road. It acts on the car in the opposite direction to the friction force acting on the car.
Newton's third law of motion explains action and reaction forces. The third law states that for every action force, there is an equal and opposite reaction force. Imagine hitting a baseball. The bat exerts a force on the ball.
The reaction force in this scenario is the Earth's gravity pulling on the Sun. According to Newton's third law of motion, for every action force, there is an equal and opposite reaction force.
An equal and opposite reaction force offsets an action force, according to Newton's third law of motion. This means that for every action force applied, there is a reaction force that acts in the opposite direction.
The idea of a reaction force comes from Newton's third law; "If object A exerts a force on object B ,then object B will exert an equal but opposite force back on A". In many problems some of the forces are considered as the "initiating" force or the applied force. When you consider a force as being applied, like a bulldoser pushing a rock, then the force which must act back , the rock pushing back on the doser, is called the reaction force. Sometimes you don't really have an initiating force but it still convienient to think of one force as the force of interest and the back force as the reaction force. There is no single formula for reaction force since it can apply to any force. For example, the earth attracts you with a force mg (your weight), then you can think of the reaction force as you attract the earth with a force -mg; equal but opposite.
"action/reaction" does not mean " force". "Applying force" is an action, not the force itself. So, applying force will create a reaction, which may or may not balance the applied force.
The name often given to the force exerted by the first object on a second object is the action force.

Reaction Force.
a reaction force
A reaction is not a separate force; it is a force that occurs as a response to an action. In the context of contact forces, a reaction force is the force exerted by an object in response to a force acting on it. It is a contact force that arises due to the physical interaction between two objects.
The force acting on an object "A" from outside is action force , and the reaction force is the force exerted by A to the outside object . Therefore, it is obvious that action force and the corresponding reaction force cannot act on one and the same body.
Reactive centrifugal force is not the same thing as centrifugal force. Reactive centrifugal force is the reaction force. It is the reaction force reacting to a centripetal force.
According to Newton's 3rd law, every force has an equal and opposite reaction force. Therefore, the reaction force on an object, is the exact same force it applied on another object, with the reverse direction.
The reaction force is equal in magnitude and opposite in direction to the force your foot exerts on the ground. This reaction force is what allows you to push off the ground and move forward.
The speed of a given chemical reaction is directly responsible for spontaneity of the reaction. The reaction force and effect is contingent upon the speed of the reaction. The faster the reaction, the more force will be produced.
