1. The reactants nature
A) Kind of bonding (ionic / covalent)
The reactions of ionic compounds are fast as it occurs bet. ions where they
dissociate completely into ions on dissolving.
The most reactions of the covalent compounds are slow as it occurs bet.
molecules where they are difficult to ionize on dissolving.
B) The exposed surface area of the reactants
As the surface area increases, the speed of reaction increases.
