heat friction
No, erasing a mistake with an eraser is not a chemical reaction. It is a physical process where the friction of the eraser removes the pencil marks from the paper.

Sliding Friction
The type of friction that occurs when an eraser is rubbed across a sheet of paper is sliding friction. The surface of the eraser rubbing against the paper creates resistance and generates heat, which helps in erasing pencil marks.
Sliding Friction
sliding friction
Friction between the eraser and the surface creates heat and abrasion, causing the graphite particles from the pencil marks to stick to the eraser and be lifted off the paper. This process helps to remove the marks and erase them effectively.
This kind of friction is referred to as drag, or air resistance.
Sliding friction requires more force to overcome its friction.
