Rate of reaction

Rate of reaction

What factors affect the rate of reaction?


Factors:

The temperature can affect the rate of a reaction
Concentration affects the rate of the reaction because the level of the hydrochloric acid is higher
A catalyst is needed for the reaction to speed up
The surface area increases the space for the molecules to increase the rate of the reaction

Background knowledge:

Temperature:

At low temperatures, particles of reacting substances do not have much energy. ...

Concentration:

Rate increases with concentration if the concentration of the acid is increased the reaction goes
faster because in dilute acid there are not many acid particles. ...

Surface area:

A reaction between magnesium and acid would be much faster if the metal was to be powdered. ...

Catalyst:

A catalyst speeds up a reaction, only some can be done like this not all reactions with a catalyst a
collision needs less energy to become successful. The result will be that more collisions are more
successful so the reaction is now faster.
