What are the factors that affect rate of reaction?

 i)       Nature of the reactants:

(ii)     Concentration of reactants     

(iii)    Effect of temperature   

(iv)    Presence of a positive catalyst  

(v)   Presence of negative catalyst

The rate of a chemical reaction is affected by several factors like:

1) Concentration of reactants

2) Pressure

3) Temperature

4) Catalyst

5) Nature of reactants

6) Orientation of reacting species

7) Surface area

8) Intensity of light

9) Nature of solvent
