Which of the following does not influence the rate of reaction?

Options

  1. AMolecularity of the reaction
  2. BTemperature of the reaction
  3. CConcentration of the reactants
  4. DNature of the reactants

Correct answer

A. Molecularity of the reaction

Step-by-step solution

Nature and concentration of the reactants its and temperature of the reaction influence the rate of reaction. But molecularity does not affect the rate of reaction as it includes the number of atoms, ions or molecules that must collide with one another to result into a chemical reaction.
