The factors that influence the rate of a chemical reaction are known as 'rate determining factors' or 'rate limiting factors'. There are several factors that influence the rate of a chemical reaction. These include:

Nature of the reactants
The nature of the reactants refers to the type of chemical compounds involved in the reaction. Some chemical reactions occur more easily than others because the reactants are more reactive. For example, combustion reactions occur very easily because the reactants (oxygen and fuel) are very reactive.

Concentration of the reactants
The concentration of the reactants refers to the amount of reactants present in a given volume of the reaction mixture. Increasing the concentration of the reactants will increase the rate of reaction because there are more reactant molecules available to collide and react with one another.

Temperature of the reaction
The temperature of the reaction refers to the heat energy present in the reaction mixture. Increasing the temperature of the reaction will increase the rate of reaction because the reactant molecules will have more kinetic energy and will collide more frequently and with greater force.

Molecularity of the reaction
The molecularity of the reaction refers to the number of molecules involved in the rate determining step of the reaction. This factor is not a direct influence on the rate of reaction, rather it is a way of describing the mechanism of the reaction.

Conclusion
Out of the above-mentioned factors, the molecularity of the reaction does not directly influence the rate of reaction. Rather, it is a way of describing the mechanism of the reaction. The rate of a chemical reaction depends on the nature of the reactants, the concentration of the reactants, and the temperature of the reaction.

No, the rate of reaction is independent of the nature of reactants. It depends upon conc of reactants, molecularity and temp. Refer to class 12th ncert chemistry part 1, chapter 4 chemical kinetics.
