to my dearest fyra;
size of reactant..
the smaller the size of reactant,the larger is the total surface area exposed to collision.
concentration of reactant..
the higher the concentration,the higher is the number of particles in a unit volume.
temperature of reaction mixture..
the higher the temperature,the higher is the kinetic energy of reactant particles.The particles move faster
catalyst..
catalyst provides an alternative path of reaction which needs lower activation energy.
1.the frequency of collision between particles increases.
2.the frequency of effective collision between particles increases.
3.the rate of reaction increases.
*utk catalyst start dr no.2..yg laen start dr no.1
**tintin**
