Rate Of Reaction's

An explanation

  • when two reactants meet in a chemical reaction the substance it will result in is called "the product". The amount of product made every second is the rate of reaction.
    many different things can affect the rate of reaction, for example:
  •  The surface area of any solid reactant.
  • How often the particles hit each other every second (the collision frequency)
  • Whether the reactants are solid, liquid or gas.
  • The pressure of the reactant if it is gas.
  • The amount of reactant dissolved in every cm3 (the concentration)
  • The temperature of the reactants._

Higher temperatures mean that the movement energy (the kinetic energy) of the particles is greater, and so  more of the collisions lead to a  reaction, there are more effective collisions.


Reactions may go slowly or quickly. Corroding metal is an example of a slow reaction. when the latest spy films shows a car going up in flames, it is showing a fast reaction. Also a match burning is a fast reaction as well as a cake rising.
