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.
