#(i)# #"Temperature"#...clearly, the higher the temperature, the greater the rate of chemical reaction...
#(ii)# #"Concentration"#...clearly, the greater the concentration of reactants, the greater the rate of chemical reaction...
#(iii)# #"Catalysis"#...catalysts can promote or hinder the rate of the reaction, by facilitating the path to equilibrium...
#(iv)# #"Homogeneity"#...clearly, homogeneous reactions, in the gaseous or liquid state, will be faster than in homogeneous reactions occurring between solid and liquid or gas, liquid etc....
