Answer:
Do you want me to give you the definition in math, science or just what a product means because there's different types.
Increase the Surface Area of the Reactants. Increasing the surface area of the reactants increases the rate of the reaction. More surface area means more collisions of the reactant molecules and an increased rate of the reaction. This occurs when reactants are made to react in powdered form
Answer:
At the time of Rutherford's experiment, the accepted model for the atom was the Thomson plum-pudding model of the atom, in which the atom consists of a "sphere" of positive charge distributed all over the sphere, with tiny negative particles (the electrons) inside this sphere.
In his experiment, Rutherford shot alpha particles towards a very thin sheet of gold foil. He observed the following things:
1- Most of the alpha particles went undeflected, but
2- Some of them were scattered at very large angles
3- A few of them were even reflected back to their original directions
Observations 2) and 3) were incompatible with Thomson model of the atom: in fact, if this model was true, all the alpha particle should have gone undeflected, or scattered at very small angles. Instead, due to observations 2) and 3), it was clear that:
- The positive charge of the atom was all concentred in a tiny nucleus
- Most of the mass of the atom was also concentrated in the nucleus
So, Rutherford experiment lead to a change in the atomic model of the atom, as it was clear that the plum-pudding model was no longer adequate to describe the results of Rutherford's experiment.
