The correct option is D Molecularity of the reaction
Factors influencing the rate of the chemical reaction are:
(a) Nature of the reactants:
(b) Temperature: (Increase in temperature increases the rate of the reaction.)
(c) Concentration of the Reactants: (Greater the concentration of the reactant, the greater will be the rate of the reaction.)
(d) Surface Area of the Reactants: (Greater the surface area, the greater is the rate of the reaction.)
(e) Catalyst
